It is not related to quantities of information such as bits.
A document is not the sort of thing that can have measure; an
observation is, and with computationalism, a computation is. I suppose
that to a structuralist such as Wei Dai, the information written on a
document can give rise to consciousness and thus have measure.

Again, documents don't have measure in the first place. Measure
is the amount of consciousness, which I take to be proportional to the
number of implementations of a computation. Effective probabilities are
proportional to the measure, but the measure is a more fundamental
concept.

(If by copy it is understood that one makes a working copy of a
computer and runs the program, then) yes.

(as above) yes, at least that's what happens in my view.

Value is subjective. To a 'good' person, measure does have
value. 'Significance' in my above quote refers to the fact that a single
point, relative to an infinite number, has measure zero. You can say that
the switch from finite to infinite numbers forces us to use a renormalized
way of quantifying measure. I.e. if we define the measure of Bob at t0
to be 1, and in our model that person has N copies, then as N approaches
infinity the measure of a single copy approaches 0. But a person with 2N
copies would have measure 2, and this ratio of 1:2 is preserved in the
limit.

It is dimensionless. You can change units by multiplying it by
any constant number, and that number can be infinite as in the above
example with Bob.
