Quick home electric question

That explains the massive power outage in the town next to you ! Lol
It's about to get worse

I checked, all the 200 amp breaker does is kill power to that unused meter base in picture #3
I guess that means I can rip that whole things out, no?

If you look at this picture, you see 2 30 amp breakers in that panel (top right locations)
The top one is the one I wired up for the generator
The second from the top is actually the feed Into that panel

When I kill that breaker the entire panel goes dark

Does that make sense?
Or was that a bonehead move from the previous owner?
I did not check yet, but i presume that breaker is fed by breakers 12/14 out of the main box

Would it make sense to leave that as is, or should I rewire those two wires to the lugs above the 200amp breaker ?
