Every "measurable" "thing" exists within or of an electric or magnetic field.

Taking a measurement involves "consuming" or "absorbing" part of said fields.  It's how "fancy" or electronic measuring devices work (not rulers or pencils).

This explains why:

   "Taking a measurement of a system affects or alters the system."

[Reference the "Uncertainty Principle"]

Too bad everything can't be measured with "tape".

Nearly everything we need can be built with it, so maybe the sentiment is backward.
