If you as a DM mention it before the game starts that:
a) you don't want highly optimized characters
b) you might ask a player to change his character due to being too good
c) you might retract/change magical items due to balance
I have no problems with it. Arbitrary changes during the game is not good though, but can be acceptable if the DM sits down and explains why he wants changes done.
