But most over-used feature of bitcoin by the scammers, money launderers, terrorists, drug dealers, arms dealers, Child pornography makers, PII sellers, contract killers etc.
A meaningless argument. Privacy is the most over-used feature of cash by the scammers, money launderers, terrorists... etc.
The entire point of money is that it can be traded for goods and services. The entire point of trustless, decentralized, money is that it can be traded for
any goods and services. Drugs are the second largest market in the world after food. Every fiat in existence has been used to buy drugs for thousands of years. If bitcoin
couldn't be spent on drugs, then it's not really money, and it definitely isn't decentralized money.
A minority of bitcoin spending is on illegal goods and services, and of all illegal goods and services being bought, a tiny minority of them are bought with bitcoin.
