Yes, however using a command wouldn't change the item data in the same way. And minecraft only remembers a certain number of repair times. It's the same with enchanting, almost like an ID cap. You can only have so many modifiers as it were.

But in the past, /fix has a special tag on it that made the durability drop to 1 if someone other than an Elite+ picked it up. In that way, it basically prevented people paying Elites to /fix items for this. Couldn't this apply in a similar way to make it so that more meebles were paid each time a pickaxe with a /fix tag was fixed?
I honestly have no clue - just throwing the idea out there.
I think Vexmae's idea of having /fix as a command for everyone that costs meebles being a good idea. Perhaps to make it even more of a perk, it could cost less the higher your rank, or increase exponentially less - not sure how that'd be coded though.
