Higher ground clearance makes it easier to enter/exit for the average Joe

Maybe if the average Joe is 70 or severely overweight. I weigh over 130 KG (300 lbs) and have little problem entering/exiting a normal car. Tiny hatchbacks can pose an issue if getting in the back seat, but that's about it. They also make crossover versions of those tiny hatches and they're no better for me.

better visibility for new drivers

Not necessarily. Many crossovers have massive pillars, making visibility worse. As they're heavier than a similarly sized normal car, they need to be able to withstand more force in a rollover (which is also more likely to occur). Smaller and lower cars are actually better for newer drivers because they're easier to control properly if you have to abruptly swerve, stop, etc.

and the feeling of a more spacious interior

You actually get less interior space for more money, generally speaking

more ride height helps with potholes/bumper scraping too

The average crossover SUV has barely any more clearance than a non-sporty sedan or wagon. I've done mild offroading in a Chrysler 300M, a sports sedan. I've driven cars like that to places where most people wouldn't dare go in a Toyota RAV4 or a Nissan Qashqai, despite the little bit of extra ground clearance those cars have. People don't grasp the capabilities of their cars.

but really not every car buyers care about driving dynamics, or suitability for track days, or whatever

You mean comfort, cost, interior space and fuel economy. You get a better balance of all those on a normal car compared to a crossover for the same price. I don't care about suitability for track days either - if I did, I'd be buying a tiny hatch or coupe, not a floaty luxury wagon like I currently drive. Which has better (more comfortable, not sportier) suspension than any crossover I've tried and I didn't even get one with the air suspension.

The auto industry pushes crossovers because they can make significantly higher margins on them. Truth is, you'll get much more car for the same money in a wagon compared to a crossover. Example: The MB GLC costs about as much as the E-Class, but the latter is significantly comfier and roomier, because the GLC is based on the smaller C-Class.

People tell themselves all kinds of lies to justify buying SUVs, but the truth is, they buy them because they're more of a status symbol thanks to the height.

And yes, I realize there are people who actually need the extra height, but those make up for maybe 5% of crossover buyers. And anyone who wants to actually go offroading, is better off buying one of them all-terrain wagons with adjustable height. Comes with the comfort of air suspension as a bonus. And they have all-wheel drive, unlike the average crossover (the more budget-friendly ones, even if they do have AWD equipped, don't really have proper AWD, the rear wheels only do any work if the fronts have already broken traction).
