Blockchain Question ?

So I just wanna put this out here and I hope to get a response. I was thinking miners on any crypto network basically connect and verify transaction in the blockchain right? , what I want to know, is that say governments decide to come down hard on crypto currencies and decide to regulate everything, is there any way to stop a miner from connecting to their blockchain network, for example, what if the internet service provider blocks the miner from accessing that specific network ?

Could this threaten the continuity of cryptocurrencies?

Please resteem for more responses
