VMC requirement more restrictive in controlled airsapce?

Can anyone please explain why the VMC requirement is more resrictive inside controlled airspace than when OCTA?

This makes absolutely no sense to me. When OCTA, with no control or radar services, you are able to fly with your tail fin in the cloud as you are "VMC". But as soon as you enter an area where you now have control and a radar service providing deconfliction and traffic awareness, then you suddenly need 1000' of vertical separation from cloud?

This limits low level operations substantially, especially when looking at the legality behind the IFR visual departure. According to AIP / FIHA, you cannot do a visual departure IFR unless you can maintain VMC until you reach LSALT? This makes no sense either. What if you don't even want to reach LSALT? You are IFR, as long as you can avoid the ground yourself, this should be permitted.

If anyone has info on how this VMC requirement inside controlled airsapce (specifically in regard to lower level ops) was determined, I would be very interested.
