Is this a joke or just a demonstration of ignorance? The name Obamacare was not given to it by Obama, but by opponents of the law. The Obama administration just leaned into it. Blame conservatives if the name bothers you, not Obama and his administration from the time.
I will never understand why NASA doesn't build at least two copies of expensive space telescopes like this. One single launch failure and boom (literally), the entire project is a failure? It wouldn't double the cost assuming they do it with even a modicum of efficiency and intelligence. And hey - assuming that the launch goes smoothly, you can get double the benefit

For some tasks, surveys in particular, field of view is critical. You would need many Hubble telescopes to do what Roman can do mapping everything out there. "What really makes Roman stand out is that it is designed for wide-field imaging. The cameras on telescopes can often only detect objects in a very small patch of sky. If we use the size that the full moon appears in the sky as our guide, Hubble’s field of view…
As to speed, it is not just the camera view that makes NGR faster but also physical factors such as not having to wait for earth to get out of the way.

Any space telescope with a mirror, is a different story, e.g.
https://science.nasa.gov/mission/webb/webbs-mirrors/
The RST has an 8ft mirror. The mirrors have to be ground and polished in a clean room to tolerances that are the highest in the world. I vaguely recall it's a square law or worse - for radius-to-time-to-polish. So you're paying for time, and you're paying for the expertise of one or two custom built places that can manufacture them.
Part of the story is everyone being shocked at being under budget and ahead of schedule. I don't know everything, but I think this is reasonably attributable to the fact that this is a retrofit of an obsolete spy satellite. The leftovers of the security sector will be the most advanced scientific space surveyor. I have to wonder what things would look like with different priorities.

Thank you! From talking to a contact working with JWST, it sounds a bit trickier in practice. The data are public, but with Roman the idea is that you must process them on their computers rather than download everything locally, and you pay for the compute/storage you use.
that's horrifying! what if you want to work on the processing algorithms themselves? can't you access the raw input data?
