One way to look at it is to think of you standing in a flat prairie.
There's no mountains anywhere nearby, just flatness. Let's say you
wanted to create a hill from the flatness? Well, you'd have to dig out
some dirt from the ground, and pile it up on another section of ground.
After a while you'd have a hill in one section of the prairie, but you'd
also have a hole in another section of the prairie -- positive and
negative, balances each other out.

But it would take energy to dig the hole and move the sand.
So this shifts the problem, but does not solve it,
Or am I missing something here?

Then look at it like a roiling ocean, rather than a rigid ground. From a
distance the ocean looks flat, but close up there are waves in it. At
some point a tidal wave might travel through it.

There exist freak waves too, probably some point where all the wave frequencies
add up at a maximum of the wave form...
