While what you're saying sounds nice, your theory has nothing to do with practice.
In reality, the ultimate source of this problem is the mismatch in speed between silicon logic and silicon memory. This is why your CPU ends up doing all sorts of tricks like caching, branch prediction, speculative execution to compensate for slow memory.
