Extrapolate from any one of those systems beyond a given point, and one runs into conflicts with one or both of the others, many of which (as far as I know) to this day puzzle the heck out of all persons who are competent to puzzle over the same.

I'm not sure where you're going with this, but I think the analogy really doesn't hold up very well, since you're dealing here with three different realms of physics, respectively,

(1) Classical mechanics
(2) Relativistic mechanics
(3) Quantum mechanics

Within their own domains, they are all following the "local laws" of physics. One can transition to the classical laws by taking the relativistic and quantum laws to the "proper limits". There isn't much of a "puzzlement" here.

What has not yet been achived is to develop a "unified field theory", one from which all others can be derived by imposing the particular conditions for each.
