Wasnt saying its not possible, just that it wont matter. People in disaster areas arent wondering how they can get some bitcoin. They are wondering where to get food, water and shelter.

Survival Rules of 3:

3 minutes without air

3 hours without shelter

3 days without water

3 weeks without food

Bitcoin fixes none of that. And all that pedal power uses (wastes) what would be very precious calories which need to be conserved since food would be limited. Think Palestine right now. How many are in desperation to get bitcoin? I would say exactly zero as they need the previously mentioned necessities.
