I was thinking, I love bitcoin - its a great way to do business. But a problem I see with it is the fact that its so easy to get robbed. I mean, you buy some goods with bitcoin over the net, send the BC and nothing arrives... waddya do? At least with cash you have a chance to bash the guy or see the goods and with paypal you get chargeback and reputation.
Your assessment is right. The same goes with credit cards. You are paying a hidden fee for an extra service which is being charged to the merchant and which benefits the buyer. And I, admittedly, enjoy using credit cards for that reason to merchants that will accept them (and never use debit cards).
It is very possible that one day some company will offer these services. The problem isn't with Bitcoin, the problem is that these services do not yet exist for Bitcoin. The ability to charge back is part of the service offerings of PayPal etc., and isn't inherent in the dollar itself.
