Isn't that the beauty of self hosting? How could anything be enforced on user-controlled servers? Practically everything self-hosted is open source and how would enforcing anything would even work?

New laws comes to mind. If a government decides to try to outlaw encryption again, cloud/hosting companies located there wouldn't have a choice but to comply, or give up on the business. The laws could also be made in such way that individuals are responsible for avoiding it, even self-hosters, and if people are using it anyways, be legally held responsible for the potential harms of it.
The problem lies with people who are technical enough to self-host, but might not be confident enough to fork/make changes. Maybe you could switch services, but there's still just enough friction/soft-lock in to actually migrate.
You are right though, it gives significantly more control to users. It's just realising 100% of the benefits that might be trickier.
