If it were up to me, I'd launch seven Hubble replacements named after each of the astronauts lost in Columbia.
Question is, could it reasonably have been guessed at the early stages that it wasn't. Decades of hindsight gives you, pfdietz, a very privileged position.
It could, and it was.

Easterbrook again was pointing this out, in the August 17, 1987 Newsweek.
"The shuttle is a superb technological achievement, and it's flown by brave, immensely competent men and women...
But what's it good for?"

The article was pointing out that going with cheaper expendable launchers would have been a much, MUCH better idea. And so it proved.
(This article is one of the reasons I wrote "largely" in the comment above.)
At any point after this article came out, cheerleading was irresponsible.
Journalists might be forgiven for not predicting how uneconomic the Shuttle would be to operate, at least before this became painfully obvious a few years in. Even the critics on Capitol Hill like Mondale and Proxmire missed that; they focused more on development cost. But the Shuttle would have been a failure even if the development cost was zero.
