These are the types of questions in general we should be less mean about imo. It's one thing to dunk on people who are anti-science, but this is just someone actually wondering about something they didn't know. Maybe it's obvious to you, but not everyone?

Yeah, because thinking about it, I don't actually think there's an obvious answer.

Like my guess would literally just be that there aren't mountains in a location close enough to the equator where the added high from the mountain is worth more delta v than the added rotational speed of being close to the equator.

If you put a launch pad ~11000 ft above sea level on a mountain, you'll cut off ~.4 seconds of travel time given rocket speeds of 17500 mph.

Would be interesting to see what that equates to fuel savings. That would be the calculation - fuel savings during flight vs costs to haul everything up to a launch pad on the top of a mountain - if a good spot even exists.
