I am not suggesting this is a perfect analogy but I think looking at a framework that is similar to an insurance product is more palatable than tail emissions. No one knows what the revenue profile of miners looks like far into the future, are they getting paid to balance grids, capture methane, what are fees, what has happened with integration into appliances and industrial machinery where no excess energy needs to be used to mine etc.
I am not speculating on any of this just on the idea if what comes out of all of that is insufficient at securing the network then paying to mine like you pay to insure your house is more palatable than tail emissions even if they are effectively the same.
