I'm arguing against making a repair that needs to be done 3% of the time cost $200 more in order to save $0.05 on the price of the device.

Labor specialization is supposed to make things more efficient. You have some expert who can do the job in five minutes that would take you an hour, and then you can justify paying them ten times your own hourly rate for those five minutes.

It doesn't do any good to cause something to take the high-paid expert an hour instead of five minutes, all it does send the device to the landfill because the repair becomes uneconomical.
