I think you missunderstand something :
CCP don’t do that only for capital proliferation. They do the nerf beacause they think it’s the best way to give to pvp player activity in LS and stop the amount of player who are upset beacause “LS is deadland”.
They also think to “reward” player who will use MTU by looting wreck with reprocessing, and so make pvp player could kill mtu and steal some loot.
CCP try to solve a lot of symptom of EVE online by over nerfing things. The problem with that is Lotka-Volterra model : They haven’t understand how it work, and the faillure will cost us a lot of player soon.
