The problem is that greater relative wealth turns into greater absolute power, a power which preferentially hoards limited resources whether you need them to survive or not.

If everyone was rich enough to own a planet.. but the richest owned all the planets with food on them, then you are screwed the next time a famine happens and they are not.

Besides: the majority of people would be much better off absolutely if there were less inequality given a fixed amount of wealth. So at no point will people not have a reason to consider inequality a problem unless they are wealthier than average.
