That isn't what patronage is, though. Patronage is giving money to an artisan to support their art. Supporting their art does not, and never has, included a physical return on the investment. Classical artists worked for years without anything to show for their noble patrons, and often never produced something the patron got to show.
A product is expected, but it is not promised. Not by default. That's not patronage. That's pre-ordering.
I was also not just including patreon's cut in the estimate (which was, I admit, super fuzzy, because I don't really care about the exact end total). Governments also take taxes, and a number of other third parties could get involved in situations Komi probably isn't currently in. The economy is not simple, and revenue doesn't directly translate into income with a simple equation.
