I did mention these rose-tinted glasses, right? Some people have romanticized views about how certain things are supposed to go or be, regardless of the subject. Eventually reality sets in and they go "well shit".
If the universe is fully procedural and quasi infinite, I mean sure, have a go at a month long space travel, going for that really far off planet, for the sake of breaking some suspect record or roleplaying some weird fantasy. If not, people should stop advocating that this idea supposing to become a general rule is actually good, because it is definitely not.
But anyway, last I remember, JC mentioned in one of the Youtube videos that the in-game universe is going to expand gradually.
