I remind readers that U(x), uncertainty in position, and U(p),
uncertainty in momentum, are standard deviations or variances in the
most sophisticated versions of HUP (by Erwin Schrodinger for
example). So the HUP people's viewpoint would lead to a "diagonal
thread" (or pseudo-diagonal thread) of "opposite" variances across
unrelated probability distributions, which is so implausible that it
can't be seriously considered.
This doesn't mean that momentum and position can't behave "oppositely"
ever. At the macroscopic level, we can actually create momenta and
positions that satisfy almost any criterion of "oppositeness" or
"similarity". Some of them can be "opposite", and can remain that way
if the physical conditions hold. Some of them can be very similar,
and can remain that way if the physical conditions hold.
