Based on the number of people that post here, and personal experience, I feel your assertion is without merit. If the machines are that fragile, this place would be full of complaints, warranty claims would be rampant, and Apple would not have people jammed in the stores buying the machines.
I had a MacBook Air, M2, that traveled with me many times, including too trips to Europe. The machine was never babied, nor was the machine abused. The machine was in excellent condition after two years of use.
