I too treat others the way I would like to be treated, unfortunately, some do not live by that simple tenet. The point, PayPal offers some level of protection from unscrupulous individuals. Had I sent a moneyorder to the individual for the items I purchased, I would have little if any recourse.
Try filing a complaint with the U.S. Postal Service for mail fraud, it would be an effort in futility. Nothing gives you 100% protection but you expect people to trust you enough to send a moneyorder or check, is your level of trust the same in them? If so, send them your goods while you wait for the moneyorder or check to arrive.
There is always risk, PayPal reduces it to an acceptable level their political stance notwithstanding.
