> At the end of the day it seems to me that any free society that supplies energy as a service shouldn’t be dictating what individuals do with that electricity as long as they pay for it.
This doesn't compute for me. We can (and do) have a free society that still has regulation. In fact, it's probably necessary for keeping it free.
Regulating resources is also critical---e.g., overfishing, mining, logging, etc.
Finally, I would say it's not the particular usage of electricity that should be banned here, but rather a particular action which currently has a negative* effect on society with no known positives beyond enriching a small number.
* If you want to argue that bitcoin currently has a positive effect on society then that's a separate argument. I'll actually concede if you show proof that its usage is driving solar up to a point that would not have been achievable otherwise, considering that fossil fuels are still predominantly used.
