I have to correct myself. Bitcoin doesn't need merchant protection, because transactions are irreversible. Paypal can provide buyer protection, i.e. chargeback

  > Bitcoin doesn't need merchant protection, because transactions are irreversible. They first have to get confirmed and that can take a long time on BTC. Replace By Fee offers another attack vector on transaction finality. Other than those two very important points, I completely agree with you.

  This is true. There really isn't a built-in way to do chargebacks and in practice this can suck if you live somewhere where that is your only recourse if you get scammed.
