What I do to my own body shouldn't affect you. If it does, that just means you need to mind your own business and get out of my life.
The truth is that we are all utterly dependent on each other to survive - every part of our life is dependent on a product or service that is the result of the combined effort of many people. If everyone got out of your life, your would literally have nothing. Whether we like it or not, what one person does to their body does effect other people, and it places a cost on others regardless of any intentional interest in their business. Should we update are laws to acknowledge that, or just ignore it?
In addition, anyone currently receiving some form of "entitlement" should not get to vote because what they're going to vote for is not difficult to guess and this situation is too exploitable and too dangerous for our long-term survival.
That would leave zero people remaining to vote.
A budget is just a method of worrying before you spend money, as well as afterward.
