Replacing an old plug for a new one with USB, sure why not DIYit. Messing around with the breaker panel to add an electric car charger or an HVAC connection, my recommendation would be to hire a professional.
The main issue with AC electricity it's how easy is to learn the basics, and get overconfident because you got something working fast (sadly here I can talk about myself). But not knowing things like the NEC Code makes a difference, and that's when you want a technician or get into the rabbit hole of learning this deeply.
Simple details as ignoring the color code, not using the right AWG for the job, can easily cause a fire, or a hidden dangerous electric shock for future maintenance, making the installation a ticking bomb.
Again, the right to repair should not be confused with "anyone can do repairs", but having the choice of hiring a 3rd party professional to do the job (or do it yourself if you have the training) outside of the original vendor.
Much the same way that someone shouldn't do plumbing, roofing, or repair their brakes if they're not capable to do so, I agree that people who are incapable ought not be doing electrical work. There's no disagreement there.
