What sort of punishment do you recommend for people who refuse to vote? if it is not guaranteed to make a difference to results, how do you justify the cost of implementing it.,
You are recommending a decision that is a leap in the dark, that you do not know what the result will be.
What sort of decision making is that, if a government was to adopt that policy for other matters you would have policies and laws made that were not good because decisions had been made regardless of consequences.
You are advocating making a decision when you do not know the results of what you are advocating
IMO that is not a good way to govern.
