This problem exists in market capitalism as well. The solution to this problem is that there will always be a massive incentive not to scam people - to earn a strong reputation and userbase - by being a legitimate business person.<p>Secondly, despite a small minority who are amoral, the vast majority of people aren&#x27;t short-term thinking opportunistic scammers. The rewards of being legit can be massive and rewarding on a long-term basis. Inspiring others to follow suit. Scamming is always a short-term, high-risk low-reward act that always exists as a niche in every market. The odds will always be against these people because the opposition is better financed and incentivized to counter their schemes.<p>Thirdly, Most consumers have a certain level of tolerance for being scammed but as long as the majority of transactions are legit then the trade-offs of reduced fees, lack of censorship, and pseudonymity will keep people using the market.<p>Finally, if someone doesn&#x27;t have the tolerance or analytical ability to not get scammed then there still exists many options outside of the market. What matters is a significant enough amount of buyers&#x2F;sellers use the service. It doesn&#x27;t need everyone.
