A superconductor doesn't stop being a superconductor if a cosmic ray ejects one of its electrons. It would however be erroneous to conclude from that fact that quantum mechanics plays no role in superconductivity.
I don't think your true objection is based on quantum mechanics. Based especially on one comment[1], I think you're making a hidden assertion that subjective experiences carry moral weight only if they cannot be explained in terms of other understood phenomena.
I'd like to examine this assertion: If someone could prove to your satisfaction that your present conscious substrate is something other than a human brain--say, a computer program with inputs provided by an advanced android body in the real world--would you consent to undergo the proverbial 50 years of torture in exchange for a dollar donated to your favorite charity?
Well obviously everything is based on quantum effects. When a transistor changes its state, quantum effects need to happen. But I don't think it's legitimate to postulate that the whole complexity of the quantum state is necessary to simulate the behaviour of a transistor.
