I don't think it's unreasonable to distinguish between what Patreon does and basic PP. Users are paying for access to the package - which includes removal of PP friction - not just for a basic PP service.
Maybe you can grift off of that ignorance for a while, but that doesn't mean it's a sustainable business model.
You can apply a variance of that philosophy onto EVERYTHING.
"Automatic transmission merely exists because the general public doesn't know how to use something like manual transmission"
"Calculators merely exist because the general public doesn't know how to use something like a slide ruler"
Note, these are analogies, I'm not saying Patreon is as innovative or world-significant as either. But it IS optimized for a very specific use case, and it does it incredibly well.
OP even calls this out - they like having different membership tiers. They're a content host for exclusive images. (Videos do tend to be offsite as unlisted Youtube videos)
