Spin can be measured but what's the use for that? You can scan a chair and use the data to reassemble. If you get the wrong spins on particles do you not get the same chair? You're looking for a function which arises at higher level.

Measuring spin is impossible without changing the particle.

You assume a human is the same as a chair? seems like a stretch

I don't understand, what is the purpose of measuring electron spin for your various atoms? Electrons are in a probability cloud, you need to scan/replicate the atomic structure, not measure the electron spin of your atoms. Doesn't really make sense for me, do you have something particular in mind or?

Do you? I already said what I have in mind. particles are not indistinguishable and "scanning" objects without destroying them not possible in this reality
