Escrow can not protect you.
Yeah, but it somewhat give the seller some level of confidence seeing the money being put in an escrow.
The escrow system that Satoshi mentioned here is not like the escrow system that we have here. Most of the escrow services has the intermediary holding full control of the funds and becoming a mediator in the event that something goes wrong.
This was not Satoshi's idea of bitcoin escrow as crypto transactions are not traceable, giving the third party full control right over the escrow fund is still as risky as doing a 2x2 transactions method where one party might choose not to obey the terms of agreements. This is the reason there are fraudulent escrow services offering lower percentages.
