He either just doesn't get it or his brain needs a check up. Again:
Paypal is reversible. Paypal is reversible. Paypal is reversible.
There. Three times in a row. Try to say it out loud or say it while staring at yourself in the mirror.
Well, i have not done any reversal on localbitcoins so far, because if i do, if someone complains about me, then i can say goodbye to my ebay account, which i use for making a living so i just ask if someone wants to sell at a lower rate than the localbitcoins guys, they are expensive but if there's no other possibility i will take them, just asked if there are some better rate in here, and I will say it for 100th time, NO REVERSAL ever done by me and never I will.
