No. Not one state less. As bad as CA is with it gone and any other then we will no longer be The United States of America.
CA is more trouble than it’s worth and it is only going to get worse. We would still be the good ‘ol USA. We only had 48 states between 1913 and 1958 and we were still the good ‘ol USA then.
However, I would insist on a 50 mile wide, USA land corridor from the NV border to the Pacific Ocean somewhere between LA and SF. Essentially splitting CA in half, but allowing CAs free travel between the two half’s through the corridor.
