One thing is that only certain percentage of world population uses bitcoin at present time and even in future it will increase but might not even exceed 30-40% of world population. So that number drastically falls from 7.8 billion. Also we do have satoshi and it is upto eight fractions available so in quantity it becomes more, as well it is demand and supply game. There will be always a seller available who want to sell only thing if demand is much higher than selling then price will keep rising.
The distribution won't still end though because babies are born everyday and they will be counted as part of the population meaning that they will also be part of the distribution which as I have said in my last post, that the distribution will be endless unless some extinction event or catastrophe happens and wipes out half of the population.
In fact, I very much hope that people all over the world will use Bitcoin for transactions. Some countries may not even have the Internet. Human nature and social ideology determine that the world may not move towards the same, it is just a good wish. Let time witness history
