Getting a fake certificate signed requires state level opposition or entities with that level of resources, and frankly if your opposition is state level, you’re fucked anyway.

Yeah like I said, if they can hijack your traffic, they can easily get a fake cert signed.

How? They would have to steal the CA key and could only impersonate the site with the self signed cert. (At least if you don’t add it to your certificate store)
The cert is self-signed. There isby definition no CA key! Anybody accessing that sight, unless they did something phenomenally stupid, is going to have to validate access by self-signed cert on each access. And that means that any MitM isn’t going to flag any alarms … because they’d be inserting themselves as a self-signed cert.
The certificate isn’t “malformed” it’s just not signed by one of the holy approved certificate authorities.
Allow me to rephrase.
I looked at the dodgy certificate and said “I’m not stepping past this point”.
You certainly didn’t miss anything, but the certificate isn’t any more dodgy than that of any other site.
Self-signed certificates are too silly to bother with. Might as well go straight http if you’re going to go self-signed.
A CA-signed cert reduces the chance of a bad actor between me and the target site. A self-signed cert opens the door to trivial MitM attacks.
Because bad actors that can hijack your traffic are unable to get a fake certificate signed?!
How would that be?

Sure, it’s even in the terminology you use self-signed. They used their own CA to sign the certificate.
The fingerprints are going to change and it will be signed by another CA. So MitM-attempts are pretty obvious.
