Can someone explain to me like I’m 5 why we want crypto as a commodity rather than securities

I don’t think I really understand what either really mean for the crypto space. I know Gary Gensler is trying to make every project securities but why is that the death of crypto. I don’t think I’m fully grasping the situation we’re currently in and I do like to try and be as informed as possible. I understand it puts regulatory stress on these coins but don’t get what that entails fully. Is it because they lose decentralization? This stuff also kind of stresses me out, as I’m sure it does a lot of you.

Why’s this Gary dude seem like he has a personal vendetta against crypto. He kind of seems like he’s overreaching his power at the SEC.
