“If you think it is reasonable that people who don’t own real property or pay no taxes should vote, that is your decision (not very smart one).”
But not all laws are laws that only effect the ownership of property and the rate of taxation. Also even those who don’t not directly own property may be paying rent so decisions about property can impact them.
OK, I am not going to argue details here. I personally like the franchize limited to taxpayers, but indeed not necessarily home owners. but the majoe limit of the electoral franchise should come from the monarchy, and exercised sparingly.
