I mean sure, that might be where the industry moves. But the reality of the world we live in today is that just about every piece of electronics you crack open is going to have a PCB with surface mount components. So, today, you should be able to obtain the parts to repair those boards when they're broken but repairable. And let's say we do get to the point where the electronics in every single device being sold are one single completely inseparable unit. Fine. Sell whatever the components are! If that means selling the electronics as one part separately from the case, do that. Most manufacturers aren't even doing that. The electronics are going to break in some devices while the case is still perfectly fine, and vice-versa. There will always be a place for repairs.
