Asking your opinion: 156 addressed holds 42% of total eth supply. What does it mean in the long run?

This is a common argument bitcoin maxis have always held against us etherians. TBH there is truth to this blame as the title suggests. 42% of btc is held in 2k+ addresses as opposed to 156 in eth. I believe this is largely due to the presale eth had in 2015. How bad this is and what can I reply back to such arguments?
