I doubt you can put a number on what the optimal distribution should look like without making some overly simplified model that necessarily ignores something important. At the same time, one could imagine a situation where wealth is so abundant that even the lowest 1% could afford any modern luxury. In that case it probably wouldn't be so bad if the top few wealthiest individuals had enough money to buy and own whole planets. They would likely use their wealth to make life worse for others, as they tend to, but that's out of the scope of this model.
