uhh my experience:

I'm using bitcoin at least once every week for buying some product/service (for last ~3 years) and I really can't call "non-reverse payment" system as advantage. Quick example: I paid part of my BFL order with BTC and part with paypal.

With BTC, I never got my money back, with paypal I simply opened dispute and they pushed them to reverse everything. I also made lot of mistakes during usage of paypal last years (wrong amount, wrong mail address) and I never had any problems to fix them.

With BTC, in last years I sent them once incorrect address (wrong copy paste) and 2x made mistake with floating point..

If you think, that non-reverse payment system is advantageous for customers/end-users, please time to time turn off your laptop, go outside and ask common people, what they think. maybe you will be surprised..
