Considering the supply vs global population = 0.003BTC per person to go around.

Do you think 0.1BTC will be like owning a mansion?
It might be or it might not.
Maybe the OP is at his highest when he posted this. You know what I mean

.
TBH, there is no mansion here. Not in the next 5 years or in the next 10 years. There is no mansion here but the only thing that we have is a bungalow. Though what the OP said is true, I disagree that 0.1 BTC will be equal to 1 mansion unless you will hold it maybe in the next 15 years possibly but right now we are very far from it and 0.1 BTC isn't enough to buy a house (you can rent one using that amount though

).
0.1 BTC = 1 Mansion might be possible but it will take time to happen or it might not happen as well.
