You can't go around being suspicious of every person you meet. Not all of us are trying to scam, some of us are just trying to do honest business.
You are correct that everyone starts out as a new user, however before it would be a good idea to accept a reversible payment method from a user, they should first build up a solid history of trading honestly with other users.
The only time I would ever consider accepting PayPal for Bitcoin is if I needed to buy something online that does not accept Bitcoin and only for small amounts (~$100) and only from reputable members that have an extensive trading history of being trusted by others with larger amounts.
So I should build up my reputation with other users, even though you're telling people not to buy from new users? Who can I buy from then? You said so yourself that the way to build your reputation is to do honest transactions, but you're advising this person to not even give my account any thought because it's new. That's not fair. You cannot build up a trade history unless given enough chances.
Unless I'm misinterpreting your advice
Sure, if the OP would be interested in using something like Western Union or another service to do the transaction, I'd be more than willing to. I'm just looking for $60 worth; if that's too high then I'd be happy to come down to a more trusting rate. I've seen plenty of scams and have been scammed personally so I can understand taking precautions and am willing to bend to them.
