And not even a business, the other things you're describing are things you have to solve even if you want to provide the service for free (well, for cost at that point. Because if you're providing media content and hiring people, the whole thing costs you more than labor). And the other things you've described are table stakes... Filtering content and handling abuse in particular, if you get large enough for anybody to care you exist. No government is going to sit idly by and let a service just become the next CSAM haven.

At the end of the day, most people don't want to put the labor in. If they did, we would have seen fediverse take off ages ago.
