a pipe 230m tall with the bottom at ground level would experience the same hydrostatic pressure as water 230m under the ocean. the pressure comes from the weight of water above it, not distance from sea level. this is literally how water towers work.

The post I replied to said the opposite - that the pressure at the surface of the ocean would be the same as the pressure at the end of a pipe going under water, if there was a pipe.
Which clearly isn’t true or we’d have a trivial perpetual motion machine.
