I don't know about you but for me and my family, I want a better and easier life, if I don't own a car today, I want to own one so as to make transporting myself and my family to different places easier, here in my country, transportion to both short and far distant places are very expensive, on a very busy day, if one has no private means of transportation, one would literally spend over 10,000 in my local currency in transporting him or her self to short distance places, while if you are going on a long journey, then budget from 40,000 to 500,000 depending on how far the journey is and also the mode of transportation, this could even get higher..
I think people meant we don't have to own a car because we already have motorbike, they not saying we don't need to own transportation at all.
But this is different with developed countries where I heard car is cheaper and convenient than motorbike.
Since you said public transportation is very experience, I can get it why you need a car. In my country I can rent a car or use Uber, it's cheaper than owning a car.
So, aside the above, like I said before, we think growth and not stagnation, it's important for humans to try new things and learn new things, get used to new way of doing things, isn't this why Bitcoin is gradually replacing fiat today?
Replacing in what? I don't see Bitcoin replacing fiat at all.
