No, launching big heavy explosive things into space shouldn’t have fewer regulations. That’s insane to think they should be able to just do it without much oversight.
Sure the safety part of it is something that should be verified before launch. But when they are launching multiple of these things and the variables are all mostly the same you don't need to do the same analysis over and over again.
A prime example is the environmental impact stuff. They have already done that multiple times. Nothing really changed. If it succeed and doesn't blow up the impact is X, if it blows up the impact is Y. Yet these approvals take weeks and months.
There are also multiple agencies that put their foot down. Famously fish and wildlife was worried starship would crash in the water and hit a shark/whale. No seriously. https://youtu.be/kS8G5D9fg3g?t=21
Then there is the story that at Vandenburg air base, they had to strap a seal to a board and play rocket noises through headphones to see if it was distressed. Keep in mind Vandenburg has been a military rocket launch site for decades. But only now when its SpaceX do these agencies put up road blocks.
