Perhaps! But what sets places like Patreon above and beyond those like Steemit and Whaleshares, is the fact that they are NOT based on the blockchain concept, but rather are moderated so as to keep unacceptable content, like porn and other such stuff off their sites. No forum that allows the posting of porn (other than porn sites themselves) has ever succeeded.
And secondly, places like Patreon do not allow down-voting, therefore authors and their posts can not be destroyed by hateful members who seek nothing more than revenge as do many Steemit witnesses.
And then of course, there is the Steemit witness system. Such places are doomed to failure before they even begin, because they are really nothing more than disguised ponzi schemes.
Is nudity allowed on Patreon?
Nudity and the human body has been part of art since the very beginning of our history. It is so intertwined that we would never even think to ask whether or not the “David” would be allowed on Patreon.
Nudity is allowed on Patreon as long as it is flagged accordingly:
If you are planning on posting nudity on your page, please mark your page as adult content. The same logic applies if your project changes with time. You can read more about how to mark yourself as an adult content creator here: Should my creator page be marked as adult content?
Content with mature themes should be marked as “Patron Only”. This means that you cannot post nudity in public areas including your profile picture, banner, tier images or about me section.

Apparently, drawings and animations of such activity are allowed.
AND, even highly suggestive borderline scandalous content is allowed on yo.utubz.
