I'm the host, and I also happen to be blind. I chose 98 doors and none of them have the car - terrible luck on my part! But probably this lends some credence to your initial guess?
Similarly, an adversarial host who sometimes opens a door and sometimes just shows you your choice can similarly mess with the odds.
It’s really due to the host both being forced to show a door and knowing which door to choose that you gain from leveraging that knowledge.
The player are indifferent to switching under your scenario. Why not, I suppose?
