More registers appear to be a good thing, in terms of reducing the total number of memory accesses a program might require

Registers are meant for performing various operations, and Memory Data Registers, address registers, index registers, data registers, Program counters, and accumulators all work in tandem to solve various purposes. And if we have more registers then we are certainly going to reduce the total number of memory accesses that a program might need.

Explanation:

Registers, as explained above, can certainly reduce the number of memory accesses that a program might need as the MDR number will increase, and so other types. Hence, in a reduced number of memory addresses, we will be able to run a program.
