>Why would losing the ability to play together cause the kick and bass to line up?

Because if they lost the ability to play together, then they would be forced to either overdub tracks played individually with a click track, OR use midi, in both of which cases the kick and bass typically lines up.

So what this say, is we get this exact "perfect line up" now, but not because musicians lost the ability to play together and sound naturally, but because we prefer these other two production techniques and audio processing that removes all natural nuance.
