Besides what others have said a lot of Patreons success comes from the value add pledges have on the platform. When you go to a creators page on Patreon you have pledges on right, recent posts in the middle, and info on the left. Half those recent posts probably say "patreons only" or "$15+ tier only". Like it or not getting sustainable patronage like that requires that the donor get something in return to capture audiences the way Patreon does. It doesn't necessarily have to be what Patreon gives you - usually exclusive posts on the Patreon page, maybe recurring rewards that cost a lot less than the pledge tier - but independently implementing that outside of the website would be at best expensive and at worst ineffective because Patreon has the patronage "mindshare" and people "trust" it now.
