Maybe I didn't say it well, but I meant, escrow functionality is not inherently (as far as I know) a built in feature of any block-chain protocol that I am aware of (i.e. BTC, ERC-20, BSC, whatever). Now, your point about an escrow service, well, that is not a "pro" of crypto vis a vis other payment mediums, because you can also escrow cash, as an example. Saying nothing for the fact that to escrow monies (either cash or crypto) for a low dollar value transaction is over-kill. Moreover, as it seems you are somewhat fixated on anonymity - incorporating a third party (the escrow service, your lawyer, whomever) into your transaction does not help with anonymity (i.e. if more people know your business, you are less anonymous).
