Well you could do the same with paper-gold. But since its value increases over time you have no incentive to prefer it over $, which have a decreasing value. Stop focusing on tech and try to think about underlying market forces.

I don't know about you, but I prefer to store the value that I work for, in something that doesn't burn 2% off each year.

And if I have to buy something, I will just trade in my value stored with the thing I want to buy. I don't see any need to go to an intermediate thing that keeps decreasing in value.

Paper money was preferred over gold because it was inconvenient to keep working with gold, not because the paper loses its value.

Said in another way, do you prefer paying for your car in bitcoins, which is likely to increase in the next years, or $, which will decrease?

Bitcoin may be good to store value (gold or land being the best), but isn't adapted for exchange, as no one wants to use it to buy something. Sellers should offer steep discount for the opportunity cost in order to obtain the money, which isn't very likely.
