> When the government disallows bitcoin/etc because of constant scams,

That's a big when. Also, which government? The only ban on bitcoin that can be effective is the one in which all countries in the world collude, otherwise holders will move jurisdictions (to stop getting robbed from the government via inflation).

> all of the transactions will be tracked and the government will know who spent what on bitcoin.

Hahaha and now you tell me how? If this was easy to do, then technologies such as PayJoin or what Wasabi wallet implements would have been cancelled already. No government can stop this.
