You can work your day job and make $20-500k/yr or pursue drug dealing and make $5-5000k/yr. I don’t think that’s actually a compelling argument for the latter even if the opportunity cost is better.
Drugs are illegal, exploits are not illegal. Selling them to someone associated with illegal activity is probably illegal, but there is a legitimate fully legal exploit market with buyers like intelligence agencies, and an illegal market with buyers that run oppressive regimes and commit genocide.
