See for me, I want members lower than founder rank to be able to claim a system for mining, other permissions aren't a big deal. No matter what rank I allow that permission to though, only founder can do so. Same goes for every other option. It makes factions entirely pointless and more of a liability than a help, as evidenced recently when I had an inactive founder come back after months inactive to grief me. 8 months worth of mining as well as everything I and my faction members had built was destroyed within a 10 minute period. The admin on the server can't even help because even though there are admin commands that supposedly allow him to kick members from my faction or otherwise change things within the faction, none of them work.
I know the game is alpha and all, but it's still damn hard to be motivated to bother with it ever again after something like that happens, especially when there are other games on the market trying to fill a similar niche.
