I mean at some point Apple made it work with their in-house ARM-based CPUs - first for phones then for laptops and desktops. But that was many years later and with a truly massive budget commitment to help the foundries and with enough volume that inhouse designs made sense and with control of the software environment on top. Not impossible but not exactly circumstances available to many companies. Sun and DEC and IBM made CPUs for their own computers too - but not to compete for basic PCs. Motorola made a lot of phones at one point but not to the degree that they could lock in top of the line fabs. It's not that the 68000 family was necessarily impossible to use in lower priced PCs by the way. Philips built the 68070 for use in CD-I and other consumer machines. And Apple and Amiga made it work for a while with more mainstream parts.
