True. However by 'being able' to spend it... and by being familiar with what it is, and could become, we better appreciate it...

Someone who has not spent it, especially via lightning, cannot value it in the future imo.

1 sat at a time is spending too

with regard to the pizzas... that assumes that the growth in exchange rate/purchasing power is something like... 100000000% which is not realistic. Not at least in many human lifetimes by which none of us today will be here.
