Any bitcoin enthusiast and supporter might always say "There is a big problem with Paypal - the charge back issue". While Paypal stays the world's largest merchant supported virtual payment network. Merchants are widely supporting it. Bitcoin has the major advantage of the non-reversal of the payment. So, it is better than Paypal. RBF may alter this to some extent. But still even if RBF is adapted, wide support of bitcoin won't stop. However, I don't want RBF.
I agree. While RBF may offer some convenience, the ultimate cost of being able to double spend this easily (and especially with the scenario outlined in the article regarding non-chronological processing) not only compromises the security that Bitcoin was founded on, but introduces a host of new problems (i.e. network division/fragmentation).
