Oh, it is definitely worth a try, I never implied otherwise. In fact, given the accesibility of the energy range and the necessarily ad-hoc nature of the various models of the Higgs sector, it would be unforgivable not to try.

If the SM Higgs is found, with no evidence of physics beyond the SM below 1TeV (including "corrections" due to physics at higher energies), I think it will be safe to say that theoretical high energy physics will have "died of success". There would be no strong case for higher-energy accelerators, leaving aside how difficult it would be to build something to probe the 10TeV range.
