Even one we reach net-zero emissions (which I agree, is proving to be an incredibly hard task politically) we still have the problem of a century of carbon emissions in the atmosphere. Getting our climate back to pre-industrial is going to require carbon capture ramping up dramatically later this century.

These projects will only make sense to operate at truly large scale once we've already shut down all the coal plants. I think what stripe is trying to do here is make early investments so that when we really need it to scale, the costs are low and the tech is mature.
