Agreed on the last point. That's part of what I was alluding to in terms of scope and scale. The smaller communities from early internet days (my experience overlaps with the time of BBSs but never included them) were pretty light on moderation. If you were a dick on IRC, you got booted. If you spouted off about politics in places that weren't about politics on phpBB, you were ignored then booted. These days, that sort of dynamic has moved to Discord, with people expecting that they should be able to say whatever they want, wherever they want everywhere else.
But I feel you're begging the question on funding. The ownership and profit model is the problem. User subscriptions can solve that funding issue in a vacuum; reality tends to be a bit messier, but I'm hoping we'll find that it works.
