An elected representative would only be able to do the things that you, yourself, have the power to do.

If these people stayed within that realm, they could never do any of the following:

• Create new taxes
• Force you to do anything
• Prohibit you from doing anything

Why?
Because neither you nor I have any right to do the following:

• Steal from other people to do things we want to do (e.g. tax them)
• Make other people do what we want them to do
• Prevent other people from doing what they want to do

So far as any political law does any of the above, it shows that the one(s) enacting it are stepping beyond the bounds of their proposed authority.

A right can not be voted away by a majority. Nor can any majority grant themselves rights that they do not have individually.
