The lunar gateway is the only mission target that I find appealing. The support for LEO economy is nice, but there is no concrete plan for it, our launchers just cost too much right now for it to develop to an acceptable level.
What about the lunar gateway is appealing to you?
IMO, it's a complete waste of time and money. Even the overt justification is basically that it'll help to politically stabilize Artemis, not that there's some sort of engineering or scientific reason for its existence.
And if Artemis is even marginally successful, there'll be lunar ground facilities that will quickly supplant the importance of the gateway - making it more of an albatross than an asset.
And if mass and diameter are launch constrained [1], why not chose an inflatable tech? Again, congress, because the defense contractors don't like inflatables. If we wanted a true lunar station, it should be large enough to live in long term, not suffer in for pork spending's sake.
There are plenty of vocal, inside critics [2,3].

Not having a window is very disappointing, I agree, but whether it is inhumane or not probably depends on the duration of the stay.
If we're going to set up a lunar orbital habitat for actual work and habitation, great for humanity, but chucking a billion dollar can for maybe a week to satisfy a congressional spend is beyond pointless.
The only reason it exist it because it allies a bunch of different interest in NASA and its partner, those people who believe electric propulsion for Mars, space station people and the micro-gratify biology mafia.
Everybody know that the Gateway and the SLS/Orion are just political buyoffs for congress, so they can funnel money into an actually innovate and revolutionary solution, Starship.
The goal is to get Starship going and then do an end-run around congress and sell them on more Moon/Mars missions, finally killing all these terrible projects like Orion, SLS and Gateway. Since the development money for those projects will have largely been spent by then, the politically usefulness is mostly gone, so they will let them go in exchange for some bullshit new bullshit contracts.
