The concept of landownership as a requirement to vote dates back to Ancient Greece, and probably earlier but this is the most ancient documented example. It is meant to weed out "stupid voters" and if we are going to assume that we need government, which I don't see as a good answer, but assuming we do, landownership for voting rights seems like a pretty good idea.
If you aren't educated as a voter, why should you be able to vote? After the Civil War many of these constructs were used to keep blacks from voting, but that doesn't mean a literacy test to vote is necessarily bad. If it is meant to keep uneducated voters out of the poll box, than that is a good thing. We can go and pretend that universal suffrage is a great thing, but I find it questionable at best.
That said, government force is an awful, awful thing.
