It would probably create an entire new wave of miners. Lower power, low noise, perfect for home mining. Perhaps get back to the rack mount style like the antminer S2 / Spondoolies tech miners so people could place it in their equipment racks and nobody would know the difference.
Yes, the governments could play whack-a-mole trying to find it all but it would never happen.
Since BTC is for people to do with what they want, it can be a store of value, it can be a hedge against inflation, it can be an investment, it can be a cash replacement. It can be whatever you want it to be. And if someone does not agree, fine you don't have to agree it's what YOU want, not what THEY want.

Precisely. People are forgetting about the difficult adjustments. If large-scale mining businesses would be ruled out, then it would be highly more viable for at-home miners. There's a reason it was designed this way — for Bitcoin to work regardless if there was a huge censorship campaign for large-scale miners.
