I think there is value in having this proposal written and published.

Even if it does not get built anytime soon (say because today‘s society thinks this is a waste of money), having the idea discussed in public helps and might inform future decisions.

For example, we still reread proposals like the Dyson sphere, space elevators, a next-gen LHC, etc. . None of this is either technologically feasible today nor realistically fundable, but it shows the ambition and might spark discussions.
