while bitcoin is already at it's 10th year since its birth, it's still considered in its early phase. there would come a day that people will be using cryptocurrencies more than fiat in daily transactions. and that day, bitcoin will be more valuable than it is today.
Maybe if all country accept it and make it legal, a lot of people can start to use it. But now some governments make it as illegal to use as payment and it can be barrier to make things that you mention realized.
10 years is STILL at an early stage for bitcoin. We can even say it's at its infancy. Imagine 10 years after fiat was implemented. I don't think people had confidence in making deals with a piece of paper and a small copper or silver coins. It's a very long process and one that would likely take decaded before mass adoption.
