That's not true. Most money laundering is in USD and then stablecoins (USDT, etc). NFTs are a thing of the past and the big majority was not on bitcoin anyway. So no, bitcoin is not a major player.
If you would completely eradicate bitcoin (which is not possible), you would solve (I'm guesstimating) 0.3% of money laundering.
It's not so much invalidating Bitcoin - Bitcoin is valid and effective. Unfortunately what it is extremely effective for is money laundering and tax evasion (which was what your original comment seemed to advocate for.)
