The vast majority of companies operate just fine without understanding anything about building codes or vehicle repair etc.
Paying experts (Ed: setting up internal infrastructure) is a perfectly viable option so the only real question is the amount of effort involved not if random people know how to do something.
Paying an expert to come set up a local CA seems rather silly when you'd normally outsource operating one to the people who professionally run a CA
You’d only need internal certificates if someone had set up internal infrastructure. Expecting that person to do a good job means having working certificates be they internal or external.

Congrats for securing your job by selling the free internet and your soul.
I’m not going to be doing this, but I care about knowledge being free not labor or infrastructure.
If someone doesn’t want to learn then nobody needs to help them for free.
