Well, some of the densest, nearest, most interesting structures are right behind the rest of the Milky Way, which causes up to 30 magnitudes of extinction in visible light, but deeper IR and UV passes through much more easily.
I think a better way to describe the issue is that much of the structure of the cosmos is only visible in non-visible wavelengths, so while calibrated, accurate visuals "like you were in a safe glass bubble" is a good category of astrophotography to continue to refine, it's a tiny slice of what's emitting electromagnetic radiation that's worth visualizing. And if cameras can convert invisible colors into visible ones, that's a blessing of a capability.
