Because governments are wiretapping the entire internet they can track down any server they can connect to live regardless of the protocol or number of indirections (this could be prevented with Freenet-style distributed hosting), but the actual downfall of the dark web seems to be web technology and outsourcing hosting. Last I checked Tor browser didn't disable javascript even on .onion sites (restricting HTML to a subset and requiring CSP would go a long way), and when sites share hosting they tend to go down all at once.

It's been years since I've used Tor browser but there were warnings everywhere about not enabling JS, and I'm pretty sure it was disabled by default.
