I'm convinced this cadence is simply part of managing the deployment and performance of content. Right now it definitely plays into the setting of the game and the discovery of what happened to the colony and the marathon. I dont see why they could'nt relax it in the future.
Tho I do find it funny that no one complains about "prestige-ing" in arc raiders being time gated when its the longer term, if not the only endgame that exists there(5 months later). Personal progress is arguably more shackled in Arc's sandbox. Like, fuck, GTFO has a somewhat similar "you gotta prove you're worthy bucko" progression to get into deeper levels and that ultimately can leave the unskilled stranded if they dont try to address their strategy and approach, forget scheduled availability
