We try to exclude a dispute with help of multisig escrow, because each step is based on reliable information and confirmed by users or blockchain data. If one side not agree the terms just decline deal.
I'm sure this will be a slow process and need try and error before it can function properly. Which escrow should you use, how can people be the escrow, or if you can code it, what kind of escrow you're trying to make, etc. I'm kinda positive that there will be at least one project famous for this thing but the process might be slow and lacking volume, just like Bisq atm.
And if that does not happen, we can always go to Bitcointalk and trade with each other.
