If 8 million people hold all the available bitcoins and no one is here to use it, everyone will ignore bitcoin and use different cryptocurrency. I don't understand why do you think that bitcoin will skyrocket if we hold each satoshi.
Hundreds of millions of people hold one or two houses but that doesn't mean the cost of house has infinitely skyrocketed. But house is a different example, you absolutely need it in your life while bitcoin can easily be replaced with another clone altcoin or with a different one.
Also, the world order isn't established around bitcoin, it's a whole different scenario. World order is not a car part to change so simply and easily. The only one who can change the world order is the one who is in charge of world order.
Well, that's a valid point. However, your example with houses is not accurate - you can build as many houses as you want and wherever you want. A house depreciates and loses value over a distance of, say, 40 or 50 years or may require repairs.
The only assets with limited supply today are land and Bitcoin. And both land and Bitcoin have their advantages. For example, if a military conflict starts on your land, you may lose it or, at the very least, won't be able to use it.
