Exactly, this will make Bitcoin have features that traditional financial systems have where all our financial activities are watched and monitored and we are asked for verifications, paperwork, and whatnot for certain transactions we make with our accounts. It is not just about giving them access to our funds that will make it troublesome, it's the fact that they can be able to keep an eye on what we do with our Bitcoins in real time which is against the decentralized nature of Bitcoin.

So in my opinion, this wouldn't solve the existing problems but it will create more problems, especially for those using Bitcoin because you wouldn't be able to use your wallet or funds as freely as you do it right now because you will know your wallet is being watched and all your activities are monitored.

Registering with a government wallet has two disadvantages. First of all, it won't be a non-custodial wallet. I don't know if there is any way for the government to keep non-custodial accounts and monitor wallets at the same time. Correct me if I am wrong. The second is that you can't spend your funds like a free bird. Because the government always monitors your transactions. They could freeze the account as well if it is custodial. So it will be treated as a bank account in Fiat. There will be no privacy as well. However, still, everyone would use a non-custodial wallet anytime. So it doesn't make sense to register with a government wallet if you don't use it. 

I don't how this would solve anything. Why would you register wallets with the govt, thereby implicitly telling the govt you're only allowed to use bitcoin with their approval, when it doesn't solve any issue?

Let's just forget about what the governments hits about the bitcoin. With all privacies and securities being observed in the bitcoin blockchain, proceeding to tie the government issued I'Ds was enough to keep transactions on tracts behold to catch up with any suspected illegal transactions in the public ledger network.
To me the government is only being aggressive with bitcoin because it's an influential threat over the fiats with the fact that it's a decentralized currency. Nothing more.

You think too highly of people. Many are just empty shells who follow blindly any authority they find. If the government says to do this the  they will do it. Most people who have nothing much to lose are like this. They rarely criticize the government and just accept anything that is given to them.
Like I said many people who are not discriminated or oppressed by the government have so much trust and confidence to their government not until of course they experience just how corrupt the government is themselves.

I guess, to me, the optional registration sounds like a good idea, but it depends on who gets access to it. If it goes into public registries, I think it should be for public figures because their finances are a matter of public interest, but regular people shouldn't be encouraged to make themselves vulnerable like that. If it's a registration with authorities (so, confidential), I believe the information should be available to the law enforcement agencies, but maybe not to everyone else in the government. Optional registration is nice, but I don't think it will convince the authorities, though, as they can just point out that criminals simply won't use this feature.

Everyone has access to Bitcoin blockchain, that's the problem. For example: A + B = C, we have no idea what is A, what is B and what is C. We might know one of them, for example A, but we won't know exactly what is B or C. If we register our wallet with government, the government will basically know both, A and B and automatically C. If that database gets leaked, you are basically naked online (thanks to public blockchain).

It's not really designed in a way to help us keep our privacy but I would say that some level of privacy is the side effect of Bitcoin. Monero is designed for having privacy protected.

It will open up opportunities but does the opportunities worth the cost that we will have to pay? Bitcoin was created to get rid of 3rd parties and if government takes the full control of Bitcoin, it automatically means returning to 3rd parties, so Bitcoin will be useless. Also, if the court will be able to order granting of private keys, basically words "you are your own bank when you use Bitcoin" will become meaningless.

P.S. We should never give up. Slaves didn't give up during terrible slavery, so why should people give up today?

While they may be using it as an excuse to ban crypto (I honestly do not know), money laundering is actually happening around cryptocurrency quite a lot. But this doesn’t mean that I stand with the government because I think it’s more than the crimes.

On the other hand, rather than registering my wallet with the government, I’d prefer to simply use fiat because it will then kill the exact purpose why Bitcoin was created. Because from registering it, they’ll long to regulate it.

Money Laundering is not happening around with only cryptocurrencies its also happening around with other methods as well because we are having many other ways which are already in use before this crypto and now after this crypto these methods are working good and peoples are using them without any problem linking this with crypto is just governments wants to have control around this with they also want to check every thing related to this which are currently not accessible for them and crypto related peoples are using them without any problem and this is the biggest problem for them.

In many countries we are having government related peoples are doing this money laundering without any problem with FATF was also introduced, but it's having no impact as this was expected so now they are trying to have related to this with crypto.

If you do this then I think your privacy is not complete. The government will monitor your wallet and will mount task on any transaction you made; although you kept the private keys with you but they know the transaction you did because of blockchain technology that will allow them to track all your transactions. They will be able to see the money laundering they want but if they don’t know any identity attached to the wallet then they have no right to interfere.
