This would remove the incentive to mine crypto on any grid that is coincidentally emitting carbon.

The carbon fee would lower and possibly sometimes completely remove the incentive to mine Bitcoin on a grid that is coincidentally emitting CO2, when the current electricity generation mix has a large share of fossil generation.

As most (if not all) uses of electricity, Bitcoin mining is sensitive to the electricity price. Introducing a a carbon tax / carbon dividend, doesn't magically make any particular use of electricity economically unviable all of the time. It just pushes the cost equilibria to different values.
