You're confusing the colloquial meaning of "theory" with the scientific meaning. A scientific theory has been tested repeatedly and can be reasonably relied upon to make predictions (see relativity and GPS, for example). The colloquial meaning of theory is more accurately called a hypothesis.

I'm not, actually. If relativity were a law, we'd presumably have unification with quantum mechanics. But we don't. Relativity works really well (well enough) in an enourmous number of areas, but not all and completely breaks down at the quantum level.

And, it only takes a single counterpoint to disprove a theory. Hence theories are signifcantly harder to prove than disprove.

What you're referring to as laws are theories that work well enough in some circumstances that needing something better isn't needed. Such as relativity to implement GPS. Newton's theorems in Principia Mathematica are generally good enough for most day to day type stuff. E.g. we dont need to involve Relativity to understand the physics being acted upon a car (thats not a Tesla roadster launched into space).

Science isnt much about coining laws. It's more about obtaining an ever more correct model of reality, and as you say, make (reasonably accurate) predictions.
