You just can't change the laws of physics.

Which laws?

The ones that involve heat transfer, compressing gasses.

I don't see any need for changes in those laws.
In fact, they support the case for more efficiency.

If it was true, every AC installer would be doing it.

Not necessarily. Money is also an issue.

So the major manufacturers of AC equipment intentionally match components
that will give less than optimum cooling?

It's a compromise, like many things in life. Bigger heat exchangers
are more efficient, but they cost more.
