> it's preposterous to assert that our current situation is entirely biological in nature
Careful on misframing the thought experiment: no such assertion was made. The assertion through this thought experiment was that biological nature has an effect, no more no less. The degree to which the effect matters is uncertain, but it is reasonable to expect it does play a role. The reason biological explanation is mentioned at all is because many seem determined to think that no such effect is possible, full-stop.
If you agree that biological differences has a non-zero effect on preference, then there shouldn't be anything to disagree with here.
