The non-cracking of the Earth demonstrates only that the tidal force is small relative to that required to crack the Earth apart, which may not be a particularly strong upper bound on human scales. :) However, RobinZ’s numbers show that it’s also small relative to human weights, so there we go.
This was my original thought until I realized that of course it cancels or else the earth would crack into pieces.
