On the contrary: A non-KYC peer to peer trade such as via Bisq or LocalCryptos often has far lower fees than the same trade on a centralized exchange, once you factor in the centralized exchange's trading fee and withdrawal fee.
On peer to peer trading platforms like Bisq, trading volume is low and it can be a barrier for people.
Time is another thing. You will have to wait for trade partners to open your offer, open a trade, and complete it. On centralized exchanges with high trading volume, it can be done in seconds but no privacy, higher trading fees and risk to have account freeze.
On peer to peer trading platforms, don't chase for high profit from newbie accounts. They are very possibly scammers.
