I think XT is great because is fundamentally allows something that was sorely needed - a way for the miners to votes.

There is no sense in trying to convince anyone to act as you want in currencies. You have to incentivize them. And if there are attacks they need to be looked at as a problem to solve.

A lot of people hundreds of years ago probably yelled 'hey don't shave the edges off gold and silver coins!!!'. The solution however, was to build ridges into the edges of coins so that shaving them off would work in practicality.

This is a battle of code and incentives, never forget that.
