You’re correct that it isn’t as good of an alternative as flossing but you’re meant to do both.
You should floss, preferably with actual floss and not a pick, and then follow that up with water irrigation. You dislodge food and break up the plaque with the floss and flush it out with the water flosser.
I miss seeing policies from other libertarians like this!
So fucking sick of the ancaps and how most people view libertarians as just an extension of conservatives that want small government now. They pretty much took over r/libertarian the last few years and pushed out the “socialist” libertarians.
