You could always flip the BGA package over and solder tiny 30Ga. Wires
>from each pad to a pin on a DIP socket...

I've done similar things for prototyping.

You would spend more time with productive coding because you would have
no design time, construction time, and definitely no troubleshooting
time. A processor of the sort he is referring to takes more than a
resonator and a regulated power supply to work.
