The elegance of mechanism is that it explains, by assuming only very simple
rule, why the numbers eventually discover the infinities in their own mind, and
correctly so.

We get an explanation why the finite number can dispense themselves of using
infinities to throw some light on themselves. With a simple ontology (any
universal system will do) we get the phenomenological reality of matter and
analysis, and beyond.

And it can be tested, and perhaps completed in case we are not machine, but
actual gods, which I doubt. That would not change much in the approach, only
make it technical more demanding. But let us not put the complexity in the
start. We can add it if it is needed.
