Mint is extremely hardy, isn’t picky about soil type, spreads quickly, strangles and overtakes whatever is growing with it, and reproduces from the roots. If mint ever goes into the ground, your entire yard will very quickly be overtaken by it even if you start ripping it out as soon as you see it. It’s basically an invasive weed that happens to taste good. Anyone who intends to grow it will keep it in above-ground pots instead. But even then, all it takes is a small sprig landing in the grass, and suddenly your entire lawn is starting to smell minty when you mow.
