As many people have already mentioned, you're essentially paying to get something produced by the month rather than paying for an employee to work on a partial number of tasks by the hour.
Creators like Nagoo are managing a business and are doing tasks that typically require several people (marketing, accounting, sound design, etc). They also have overhead to pay such as electricity, research, maintenance, business tax, insurance, etc. If a work equip breaks, they have to buy a new one. If they get sick, there is no company insurance. Plus Patreon takes a certain percentage from pledges.
Smaller creators deserve your support as much as bigger creators do. Obviously if you don't have the extra budget to donate to creators like these, you don't have to but it's always appreciated to keep the content going and improving.
Anyway, we're just waiting for a nice Psyloche model and then maybe we will animate
