A teacher can be easily replaced temporarily because *someone* has to be in front of those kids when class starts. That doesn't mean that the person will be an effective teacher. Sure you could be dropped in a 3rd grade classroom, it doesn't mean you could properly convey the knowledge to the kids, let alone if we start talking high school physics, chemistry, calculus, world history, English, etc. The difference between a substitute teacher and a great, *real* teacher is day and night.
I can do my own taxes, that doesn't make me a good accountant.
I can defend myself in court, that doesn't make me a good lawyer.
I already made that point about how that doesn't mean somebody is a good lawyer. My point is the ease to step in on these scenarios and mimic a "good teacher" , replace a "good teacher", is far easier than it is do replace a doctor, lawyer, and etc. The bar is way lower to become a teacher and it's easier to fly under the radar as one , and honestly being a good or great teacher can have nothing to do with your knowledge. To be good or great in other professions do require some level of formal education nd knowledge.
