A seller on Ebay UK has to wait 180 days to be completely immune from Paypal charge backs, not sure what the deal is with other countries. - can't waite so long so seller must take a bit of risk on him, but we will negotiate about such chargebacks if buyer will win all ebay paypal cases i will return money but again from my experiences if someone not  complain about item in first two weeks there should not be a problems.

And getting from GBP Paypal funds into USDT takes extra time and money. - yep.
