I think part of the issue is that UA bombing was relatively unknown to many, many players. In other words, they would just play the game and then be faced with a UA bombed station. That wouldn't be fun, it would just be confusing and irritating.
The entire BGS is like that, though.
I saw a case - which I will slightly anonymise to protect the guilty - where a player was convinced that Frontier had manually intervened to nerf their trade route after they'd talked about it on the forums. They hadn't at all, of course - it was just how BGS states had interacted in their standard fashion with the local markets - in this case causing a good that they were trading to disappear entirely (though temporarily) from the supplied list. That was an extreme case, but I've seen rather more cases of normal behaviour being bug reported, or otherwise complained about.
The way the markets work in Elite Dangerous is not particularly complicated. But it's got far more depth and detail to it than 99%+ of players understand, nonetheless. And because the markets respond to player actions (in several different ways), often the reason for "why can't I do X it worked yesterday?" is "other players, none of whom will face any consequences for buying the last Palladium / starting a War in the next system over / putting a Theocracy in charge of this station".
There certainly are players who would be much happier with a fully static galaxy, but that's generally not the design direction Frontier has taken.
