Dont try to make it seem like its a massive feat of engineering. Once you know how the game works, and people tell you that docked reactors are a thing you need to do to bypass an arbitrary limit placed in the game, they are pretty easy to build.
And anybody can just go download a blueprint for a docked reactor and stick a dozen of them inside their ship. Or just go look at a guide to make whatever sized reactor they want.
Docked reactors are just a bandaid placed over large wound.
Its like when I joined a server and asked why advanced build mode was limited to only being able to place down 40x40x40 maximum, I was told because it makes the game more difficult by everyone on the server, completely overlooking the fact that it just makes people not want to build things on that server, and instead do it singleplayer where they can change their config to whatever they want. Its just a pointless limit that can be easily bypassed, and for some reason everyone thinks thats totally okay when its not.
If you place a limit, and then everyone bypasses that limit because its stupid, your limit needs to change.
