I don't think there is much of in issue with corp creation at the lower end other than the fake corps.
The bigger issue are the existing dead corps littering the top of the leaderboard due to the fact old WS xp gains were wildly larger than current xp gains.
The only issue with many new corps is that some players may not integrate into the game, but many people play MMOs just to hang out with their friends and have no interest in that and at least giving those players an avenue into the game so they can be blue star fodder means that these game modes are starved even more of participants.
That being said, I think that the game does need to evolve the corporation structure, probably formalising alliances, creating an umbrella group for the mega corps to organise.
Probably also allow people to have two corp memberships slots, one as their permanent family and another for their "current membership"
While it's not how the corporation system was originally intended (Andreas originally didn't want people to be able to corp hop for bonus and Dark Nebula originally had a requirement during early access that prevented it) - the reality is that players will always play this way and the reason it was reinstated is because of the backlash
