One of the so-called features or benefits of bitcoin is the lack of any reverse transactions. But in many respects this is a great failing. Wouldn't it be better that if you voluntarily identify you as a legal entity holding a wallet address and that if you did not authorise a transaction (i.e. it was stolen or the goods weren't delivered) that there is a method to reverse that transaction?
no, no, no, no, no.. and NO
what you need is self regulation in this form:
learn who your seller is
only deal with trusted people
if you cant trust them, dont pay them
if they are trusted, they would be willing to refund you.
my personal rule for trading is, if someone on the street asked me for money and i did not know them, would i give them it?.. and the answer is the same answer for bitcoins.
EG
if i dont know the person.. no
if i knew the person and they were honest.. yes
if i came across a store that didnt have all the authentic necessities.. no
if i came across a legitimate store.. yes
