I enjoyed this read a lot, and was in a similar discussion with someone who has a crypto coin last week. There are so many theories coming out about how crypto currency and the technology it uses could potentially be applied.
I personally think the application of the technology is better than using it as a store of wealth. Of course scarcity will always be a driving factor in anything's value, but it is not the only one. And other factors such as cost of production, environment, price sensitivity, consumer demand and much more can effect the value of things.
Nevertheless, I think you have presented a great argument for Bitcoin and we will all be waiting and seeing what happens to the economy as Web 3.0 becomes the new norm.
Thanks for writing :)
