In polar coordinates the field has only a single value at a given
distance. Also, the permeability of space does not apply to the static
point charge. Granted, a truly static point charge is purely a mental
construct; however, maybe you can see my point. <g>
Of course this thought experiment violates HUP since the proton is
*not* in motion.

The E field is not a scalar field. A scalar field is represented by a
single number (magnitude) at each point; the E field is represented by
a vector at each point (magnitude _and_ direction -- that requires 3
numbers in 3-space, or 4 numbers in 4-space).
