The fact that anyone would even ask whether or not it would be moral to cure color blindness is a symptom of the fact that morality is still considered to be outside the realm of reason, that there is no way to get from an 'is' to an 'ought'.
Ayn Rand pretty much blew that notion out of the water when she identified the purpose and nature of morality in her essay "The Objectivist Ethics" in her book "The Virtue of Selfishness."
Instead of banning power hungry appliances, what if the commissars passed a regulation that citizens of California not buy anything that they cannot afford to operate. Oh, but wait. Most people do that anyway.
