Doctors don't have managers. Lawyers don't have managers. Professors don't have managers. Architects don't have managers. Bankers don't have managers.
Engineers should not have managers.
There should just be different levels of engineers.
Is that so? Here is an open position: https://www.healthcareers.nhs.uk/explore-roles/management/ro...

I think nobody should have managers, but your examples were so confidently wrong that it's hard to agree with your whole statement. I am on the opinion that any work, no matter whether "high-skilled" or not, doesn't need managers, unless that's just an euphemism for more senior employees that also do the work.
