I refuse to provide JL the constant back-and-forth that he seems to crave, but I'll make a couple points:
First of all, statistically speaking, one vote doesn't make much difference. Statistically speaking, putting $5 into your retirement account won't determine whether you have a comfortable retirement, but combined with other contributions, it can make a difference. JL's poor statistical argument is the same as arguing not to save the $5 because it really won't make a difference.
I see JL is getting back to his usual "taxation is theft" argument again. If it weren't for society and the government, you would own no "property" other than what you could carry and keep others away from at any given time. If you want to use the advantages of living in a society, pay your fair share as defined by that society. I know you would love to be able to steal without consequence, but thankfully, systems are in place (Yes, some even involve guns and cages.) to keep you from stealing.
