The number of address means literally mothing. I can send 10 coins to 10 different addresses in a minute  that doesn't mean there are 10 1btc holders 

We have no idea how many 'whole oiners' there are in reality.  Let's assume 1 million though. There are 8 billion people in the world, that's peanuts

There are roughly 58 million millionaires in the world.  So with Bitcoin at 1 million per coin, there will never be even half as many whole coiners as there are millionaires currently.  And many of them will be the same person.

The number of whole coiners will concentrate over time, obviously, as people keep trying to accumulate, invest, sell stuff in btc, etc..

The early adopter have been and are still rewarded via supply and price.

I have no idea what I will do with my Bitcoin. I already have land, homes, cars, family.

Perhaps I'll buy a sailboat. No idea.
