I'm trying to parse those sentences, are you saying there are space constraints with hubble? it's orbit isn't at a particularly special elevation or inclination, I'm pretty sure we could have several telescopes in the same exact orbit but half an hour behind with no discernible consequences. Even out at the lagrange points, you don't have to be /exactly/ there, many cubic kilometers of space have roughly the same properties that make it appealing for JWST.

It's really expensive to get telescopes up in space. We have a lot of astronomers that could use some time on a space telescope, but launching enough to supply all of them is not economically viable in any way. Sure, the stuff hubble is currently used for is not as groundbreaking as when it was launch, but we still have use for it. My point it is, we have so few space telescopes that even having time on an "outdated" one is still pretty valuable. EDIT: Maybe a better example, it's not much use for a first-world person to use a ten year old smartphone, since current smartphones are much more capable and they're comparatively cheap. Planes, on the other hand, are used for decades, since simply buying a new one is very expensive. This is despite it's tech being far superior.
