Not paying taxes from Patreon is fiscal suicide, payments are traced, they're not made with cash.
Hmm, not really, there are many ways to get payments, if they do a specific audit on the person and/or all the financial entities everywhere do their reporting, it can be found easily, but otherwise, it can be relatively simple to still hide it, since it is definitively an amount that would make a difference in my pocket ;-), but is not such a big amount in absolute (would not trigger most alerts).
Unemployed benefits in Italy are nowadays almost not existent, we're not Germany. If you refuse jobs you lose all. So it would not make sense because he has the chance to earn much more just by working at JOHN.
Yes for the first part. No for the second, if it is not declared - if he has another job and this is additional income, than it would be an extra good reason for him to keep JOHN going for as long as possible, although at the same time it is true that it could also justify the fact of not having time to work on the game.
Someone else who follows the thread/game more indicated apparently he (the author) said explicitly JOHN is his main job/main income - you guys who are frequently on the thread have more information than me, and more interest in establishing the real situation, if supporting on Patreon.
I suppose he has another more regular job, that's why he moved to Tuscany. But he probably also have bad health condition that prevents him to work also at his game.
Hmm, did not know about Tuscany, however, for the rest, it sounds like you are just throwing hipotheses, just on the line of trying to justify him for what others consider wrong behaviour - my understanding from others is that he never indicated any health problem.
Again, I do not have a direct stake in the matter, but I would suggest you keep to the historical data and forecast (AFAIK the historical data suggest the game will not be completed for at least a three-fours years, but you have to do your analysis), to decide whether you want to finance or not the game, also deciding if it is worth it for you (in this aspect, how much you like the game, and how much of an impact the support has on your pocket, could be factors).
You can exclude he could afford a rent in a Tuscan city with that income. He wouldn't have for food. Airbnb raised rental prices for everyone. This is the Italian region with most short lettings., by far, for a reason.
Actually, it is a kind of loop, but when it started, it was the reverse.
Cities like Florence are full packed of Airbnb due to the price they can charge the tourists, and that makes the housing price and rents go up like crazy, but the start, was the tourist invasion and pushing too much on it, and the greed that means people prefer to rent and sell to investors that come from outside with big pockets and buy to short rent/AirBnB, rather than at more moderate prices for people really living there.
After the AirBnB started flourishing, they did have an impact, because people saw "adequated" the prices of rents and asked sale prices to what they though they could make with an AirBnB fully booked full time (or more or less), but in place like Florence, the problem was there already some 25 years ago, before AirBnB arrived, already then people born and working there often could not afford to live there.
In Florence English and Germans were liked because they bought old run down countryside houses and restored them, Japanese managed to get by because were less and tended to be respectful, Americans were not so much liked because it was posh for wealthy ones to send their children for a semester in Florence (an USA university had a branch there for that) and spent a lot for it making impossible for normal Italian people to compete in terms of rents, but at the same time, many of those youngsters had zero respect for the city and its culture - USA university students in Europe, are known for the tendency to go "wild" with the idea that anyway when back home can play saint :-D
More AirBnB-specific is in places like Barcelona (Spain), where it got already to the strong public protests level and public authorities interventions level, in Lisbon (Portugal) there started to be some mild protest but the government made some funny proposals about "moderated rent" that basically mean they are going for full support for that type of thing and making the city impossible to live in for normal people unless they inherit an house (and sometime even then, due to maintenance costs).
But since we are (myself included, aside the amount I got from that web site, that right or wrong, is an estimate, not pure speculation) throwing speculations, if he is in Tuscany and moved there, it could also be because he inherited something, which would exlcude the rent.
Again, if you are supporting, I would suggest you forget for a moment hypotheses, even mine, and either you focus on the cost for you and what historical progress says about the estimate of by when the game will be finished, or you just take it as something a kind of "vanity expense", or if you prefer, a "worthy cause expense", in which one does not make a costs/benefits ratio

, just does it.
