I think our argument can be simplified to centralized vs decentralized systems. Ideally, centralized systems are great. 2 parties can trust and work with each other as a 3rd party is the source of truth. Any of the parties can go to the 3rd when they are wronged and need a resolution. It works great, until it doesn't. In our case, the 3rd party has a conflict of interest and can decide if party 1 or 2 can do business at all.

Decentralized, each user takes on more risk, but the benefit is that no one party is deciding who can do business and who can't. That burden is left on the buyer to decide if the seller is legit and the smart contract can be the source of truth.

The difference is that people who support decentralized systems are not trying to get rid of centralized systems altogether. They understand their necessity, but also realize decentralized systems can add some needed competition. That will improve centralized systems in the future as well.
