Take the two analogies.
One is to guard the entrance.
The other is to pull up miscreants that have got in.
Without weeding, plants eventually overwhelm a garden and this is true. But you would be a bad bouncer if you allowed every blue haired mugwump that circumvented your efforts at the entrance to frollick freely in the garden just because they got past your initial attempt to stop them. Go back there and drag the troublemakers out. The duties of 'keeping a gate' includes this.
Further on the point is if you do not do any initial gatekeeping then any subsequent weeding will be extremely hard going, analogous to removing tree roots, or initial land cultivation.
Keeping a gate is so important that if you do it wrong at the start then you are really fucked. You'll have it all to do.
It's fortunate that the personality types attracted to anime at the very beginning were quite disagreeable people, which on a genetic level selects for better gatekeeping. I don't know what the state of modern anime is. Maybe there are a lot of blue weeds in there, maybe there are only a few trying to hide else they get yeeted. But the initial selection for who you let in and who you don't is huge. I wouldn't call it wasting energy at all. You can gatekeep so hard you become dogmatic and stifle free thought and that's it's own complaint, but gatekeeping, moderate or "middle way" as opposed to having none is crucial. It's not something you could do without.
