Several other workstations from that era also had 68000s.

Ah, but those systems had mmu's. The Stanford University MMU (usually called the SUN MMU) was used a lot. But what happend during a page fault is/was FM. The original point is still valid. Those systems didn't provide much more oomph than an Amiga, but cost as much as a Sun (natch).
