1. Miners not mining anymore.
2. Government intervention for multiple reasons. One, mining consumes a lot of electricity therefore bad for the environment. But, if the consensus algorithm switches to proof of stake that will consume much less electricity. Politics and economics. Regulation matters because bitcoin cannot be tracked and it's only a question of whether the government would like to implement it.

But if comunity with switches to proof of stake, what will be with miners and BTC price? At first days BTC price was calculated according to electricity consumption for mining. And how will be with PoS?
