Please explain why.

It should be obvious. Try counting the cost of all those sockets for
all the ics, let alone what that would do to the size of the device etc.

You couldnt even use surface mount anymore either.
No reason subassemblies can not be replaceable. Connectors today can
be made extremely compact, and with LSI the active components can all
be put into one plug-in component worth a couple of dollars. SMT could
still be used on the "backbone" which could also be a low cost field
replaceable part. There is absolutely NOTHING that cannot be made
serviceable in the consumer electronics arena. Will it cost more?
Likely Does it have to? Not necessarily. Would people buy it? Smart
people would. I suspect some on this list would not.
