Property ownership seems like a pretty transparent way to disenfranchise the poor. In what way does a renter not have “skin in the game” compared to a homeowner?

I am none of these. I'm in my late 50's and have been paying income tax since I was 16. Sure, rescind my voting rights ... I'd like all my 40+ years taxes back please then.

Did the government not provide you with services (roads, police, etc) in those 40+ years?

Taxation without representation? Hellooo, Earth calling Americans, are you there?

Property ownership?

Ooooh, this is how you tip the scales further away from the progressive policies.

I own a house but I'd hate such setup.

Having children? Why not consider instead: teacher, healthcare professional, municipal worker, civil engineer, volunteer ...and all of the many other roles that make society. Being a parent isn't the only indicator of caring for others.

We already tried this in America and it’s not the flex you think it is.

What did you try?

The main issue off the top of my head with property ownership is how you define property.

I honestly can’t tell if this is satire, or if we’re running into a lack of civics education.

In the US at least, political rights are considered inalienable, not rewards. The OPs point can be extended to giving more votes to people based on their “productivity” (ie income) to society and the absurdity becomes obvious to most.
