I bet you have a problem with people not responding to your posts', right? You should find out why.
No, I'm not the one with the problem.
But I do find lots of dishonest people like you wont respond because I expose your dishonesty so well.
Again, you have the same non-issue for a flat or round Earth.
With a RE, you have areas which are below sea level which can easily flood, or areas close to sea level which can flood if more water is coming in than the change in elevation would drive out.
With a FE, you have areas which are below sea level which can easily flood, or areas close to sea level which can flood if more water is coming in than the change in elevation would drive out.
If Earth was perfectly spherical, then the water would perfectly cover it.
If the Earth was perfectly flat, then the water would perfectly cover it.
It is the same non issue.
You aren't making an argument against a RE, you are making an argument against flooding in general.
The only way it is an argument against a RE is if you believe the stupidity you have already claimed you reject, that water should magically obtain a flat surface rather than a level one.
