Your metaphor is not complete. In fact, you would be a part-owner of a piece of real estate, along with some other people (the population of a country). Then if the majority of the owners decide to pay for some other tenants (social security approved through national elections), then you have to go with the majority. You are free of course, to try and convince people that all the rent should be kept for yourself. Maybe you will be successful. Until then, you have abide by the wish of the majority and help share the burden through taxation.
