You’re digging your hole even deeper. If all the land masses on earth were flat and at current sea levels the maximum levels possible would be even less.
How so, the water would go where?
https://oceanservice.noaa.gov/facts/oceandepth.html
The average depth of the ocean is about 12,100 feet (3,688 m). The lowest ocean depth on Earth is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench.
What does that have to do with what we are discussing?
Sea levels cannot rise more than the available water allows which is a maximum of 200-400’ by any reasonable scientific estimation.
volume of water on the earth is ~1.5B cubic km. Surface area of the earth is ~0.5B square km. So if all the tectonic plates were at the same elevation, the ocean that would cover the entire surface of the earth would be 3km (about 2 miles) deep
It would spread out evenly across all of the flat land masses.
Exactly, to a depth of about 2 miles.
The tides would be immense.
The tides would not change one bit, they are driven by the moon cycles.
You cannot possibly compress the solid mass of the earth down to a depth of two miles.
You’re engaging in a completely unsupportable fantasy.
The tides would increase in height if the sea floor was flat.
That’s completely impossible. The water is drawn towards the moon because of it’s gravitational pull.
The effect is relatively shallow in the first hundred feet or so of surface water.
You are arguing apple to oranges. My statement was, scientific evidence proves the Earth was much flatter in the past. Mountain ranges were under the oceans and ocean floor have sunk. If the land mass of the Earth was flatter, like a golf ball, the existing water on the Earth would cover the Earth to a depth of approximately 2 miles deep. Verstehen Sie?
If there are no shorelines, the tidal waves would not be checked. Is this that hard to understand?
And once again you cannot compress the solid mass of the earth to such depths, it’s physically impossible.
Tidal waves are limited by the gravity of the moon and it’s proximity to any point on earth at a given time. Generally they aren’t more than a few meters in height even in very shallow water.
The biggest waves on earth are created by wind.
How did fossils of sea creatures transport to the tops of our tallest mountain ranges?
Tidal forces are based on the gravitational attractive force. With regard to tidal forces on the Earth, the distance between two objects usually is more critical than their masses. Tidal generating forces vary inversely as the cube of the distance from the tide generating object. Gravitational attractive forces only vary inversely to the square of the distance between the objects (Thurman, H.V., 1994). The effect of distance on tidal forces is seen in the relationship between the sun, the moon, and the Earth’s waters.

We’ve already been over this. At one time they were under sea while much of what is today under seas was above sea level.
There’s nothing known to science that supports you theory period.
Congrats, you’ve learned to cut and paste.
