We take for granted that motion is intrinsic to massive bodies, ..
I think the OP has discovered, by a some what roundabout route, the reason for the finite speed of sound. Quite what this has to do with conservation of momentum is far from clear, however.

I have never heard of anything that is theorized to have infinite speed - Sound we think has an upper speed limit, but we think light does as well.
It simply means that we have no other way of explaining inertial motion than to say that it is due to mass: massive bodies conserve their speed because they are massive. Its a circular answer, but it is the only one available. You have a better one?
Are you attributing a sort of intelligence to atoms?

There is no cause to that so it needs no explanation.
