Which is exactly my point. Players whose only goal is to gather "salt" will simply find new ways to ruin space legs. Your list is basically the inspiration behind my list.
Ironically, I don't think the main motivation for most players who criticize or dismiss the idea of space legs is to gather "salt" at all. I think it's that the player community has collectively realized that space legs and landing on Earth-like planets is not going to happen and a certain proportion of the fanbase who feel the need to defend Elite from any sort of criticism needs to handle that in some manner. In the past these players would acknowledge that space legs would be a useful feature but would try to come up with an argument about "dev resources" or a "ten year plan". Now that we've seen how underdeveloped and underresourced Horizons has been the argument about resources isn't viable because it's clear that FD has been intentionally putting resources elsewhere and neglecting Elite. The "ten year plan" argument also doesn't make any sense because there is no "ten year plan" and never was. So now they're left with Braben's original vision and the fact that Braben and FD are never going to come close to implementing that vision. The only real avenue left for them now is to claim that the game "doesn't need" spacelegs. Or, even more amusingly, that spacelegs would somehow be "boring" as if adding a highly anticipated feature is somehow a drawback or disadvantage.
When players try to ask what we would do with space legs, my answer is the following concept art which was used to illustrate the original vision for the game:
Neither of those activities requires station interiors at all, they only require at a minimum that we have functioning interiors for the ships in the game. Unfortunately, the ship interiors are currently empty, there is no habitable space outside of the cockpits and there isn't even any internal decks or bulkheads modelled in the current ships. To add this would take considerable dev effort to implement proper ship interiors and for that reason alone we will never see space legs in Elite. The devs quite simply did not plan for it when they designed the ships which tells me that FD must have accepted on some level that it was never going to happen. Otherwise it would have made sense to at least work out the decks even if the interiors were otherwise empty to give them a basis from which to work from in the future. Even if they did this there would still be other work to do and players would reasonably expect there to be at least a "lobby" area at stations and FD would need to develop rudimentary fps combat and mission system as well so the ship interiors would have just been a bare minimum to start with. If they haven't even designed ship interiors 3 years after the game has launched and have no plans to look at this in Season 3 then then it quite simply isn't going to happen.
If they had planned differently however it would have been a major draw for the game especially considering that other space sim games are being designed with the expectation of being able to leave your ship and interact to at least a minimal degree. Anyone who seriously tries to claim that space legs would be "boring" or "add nothing to the game" really needs to go back and look at the original Elite concept art and Braben's original vision for the game.
