The technology itself cannot be centralized but in the event of compromise, the exchange sites, mining industries, and Bitcoin or crypto related platforms will become centralized. The governments can only impose regulations for the mentioned platforms to control the activities of Bitcoin and its transactions.
Yes I think it is nearly impossible to happen in the future but if the government will find its way to centralized it then it will be possible by registering our bitcoin address throug kyc I guess.
Centralization will be the end for bitcoin. But if such an opportunity arises, the authorities will press on it to hang a lot of regulatory jokes. I'm not against "moderate regulation." And I think that if the government of any country wants to profit from the crypto currency, then it should be marketed as an independent player. And do not sit around the neck of traders / miners and collect taxes
