Btw, crypto (like bitcoin) is only an alternative because of convention.
The complete history of bitcoins is globally trackable, and people could all decide that they'll pay more for bitcoins that came from Satoshi's initial hoard, or that they'll refuse to accept bitcoins that were ever seized by the FBI.
(Yes, there are mixers. But you'd just refuse to accept any bitcoin that took part in the mixer transaction, if any FBI coins were in there.)
Apparently it powered online drug marketplaces before Bitcoin existed.

Try doing that with crypto. Who are you going to arrest?
With crypto you don't hand over your coins to a third-party for safe keeping, you instead send coins directly to one another, just like with cash.
Intentional mixers aren't even the half of it. You have large exchange operators that use a single wallet. They file KYC paperwork with governments, but that's not in the blockchain. From the perspective of the blockchain their whole exchange is one big mixer. A billion dollars goes in, a hundred was tainted, a billion dollars comes back out. The only information to trace which $100 that went in is the $100 that came back out isn't in the blockchain, it's in the exchange's private accounting database.
But if you propose to taint every coin that has ever passed through a major exchange, that's pretty much all of them.
Every on- and off-ramp provider. EU legislation has basically created a database of real person to wallet mappings (for some subset of wallets). You can't take money from a wallet if you don't know who it belongs to (if you're an exchange anyways). The checks are a bit soft (ie. self attestation and stuff), but the public ledger part of crypto makes tracking far-far easier than with traditional banks.
The end game for this is that people in the West (and whoever they can pressure) won't be able to buy crypto to buy drugs or sell it when selling drugs, making it useless on a big scale.
Second, Monero is still thought to be untraceable. In fact regulated entities are banned from exchanging it in the EU precisely because they can't trace it. (Zcash is also banned under the same law, but is considered technically inferior because not all transactions are private.)
Third, what do you even mean? Do you mean they'll go back to the last time those coins passed through a regulated on-ramp, and prosecute that person? For what? Buying cryptocurrency, then buying a legal product with cryptocurrency, is not illegal, and even if the product was illegal, the government most likely couldn't prove that. Also, the on-ramp was probably in a different jurisdiction. Perhaps for something like "acting as an unlicensed money transmitter" which is a thing they have done against users of cryptocurrencies. If they prosecute that in large quantities, will it fly?
Or do you mean they'll wait until someone takes the crypto to a regulated off-ramp, and then prosecute that person? For what - undeclared income? As far as I know, trading one cryptocurrency for another is a non-taxable currency exchange, at least in some EU countries, so they can't get you for that. And what if they declared it? Again, they might try "acting as an unlicensed money transmitter" of course. What if it never gets to a regulated off-ramp and just circulates peer-to-peer forever? It's more likely tyou think, since remember, regulated off-ramps are strictly banned.
Why do you believe it would suddenly make peer2peer cash to cryptocurrency exchanges unviable?
And if you meant tracing the Monero itself, I suggest you read up on how Monero works—and how it differs from BTC—first.
All new ones. You can buy 'fresh coins' from miners directly.
You could also exempt some 'honourable' miners (ie a whitelist) from the taint.
All kinds of conventions are possible, depending on what people want to value.
The convention that all bitcoins are equally valuable is just that: a convention. And it's not even strictly adhered to, because some bitcoins are already more valuable than others.
Hence my restriction to crypto that is 'like bitcoin'. Yes, you can use some tricks like zero knowledge proofs to make untrackable crypto-currencies. But as far as I can tell, they aren't all that popular. For currencies that offer both stealthy and 'regular' transactions (I think like zcash), the vast majority of transactions are of the latter kind.
I agree with you on targeting the on- and off-ramps. But I think you got your use cases wrong.
Crypto has two major use cases these days:
- speculation (aka gambling)
- ransomware payments
Buying drugs is pretty far down the list. And so are pretty much all purchases of normal goods and services.
