This would only make the blockchain more resistant, 51% attacks practically impossible, Firo for example has implemented this, what would be the disadvantage?

By the way I don't know if Aaron Day has commented on the reasons for choosing Zano for it point-of-sales system but I bet that fast finality was a key factor in his decision and honestly it makes sense. You can't have a serious in-person payment solution being widely adopted with unpredictable, long finality times. Now if we want to stick to online payments only, fast finality isn't as important but we have to be honest about the limitation of PoW for the digital cash use case.
