I certainly can't burn the dollars in my bank account.

Not directly anyway.

I have to go somewhere and take cash out which then I can burn, assuming the bank has that kind of money available when I attempt it and assuming I will be allowed to take it out.

Furthermore in many places such activity would be illegal.

Anyone arguing about Bitcoin without admitting that there is demand and basing everything on outdated/flowed theories is bound to be wrong with their predictions.
