Also, "we have an idea that could in theory replace them" is not the same as "we have the structures in place and shown capable to replace them".
I would want to see a lot of data to back this up--and it would have to be accurate data, including accurate data on how often the state makes things worse instead of actually helping. I don't have such accurate data on a global scale, and I don't think you do either. The state does not even measure how much harm its employees do; it has no incentive to do so.

"Replace" assumes that the current structures are providing a net benefit. If they're actually a net cost--if they do more harm than good, all things considered, which I suspect is true for the state if we could actually get accurate data on all the harm as well as all the good--then replacing them with nothing whatever would still be a net gain. Of course replacing them with something that actually did the job the state is supposed to do would be better still, but the perfect should not be the enemy of the good.
If the state actually did help the less privileged, that would be one thing. But the state programs that claim to help the less privileged, mostly don't. And even when they do, the hoops the less privileged have to jump through to get the help are ridiculous. My wife and I have a friend who is on food stamps; he's disabled and unable to work, has been for years. Every year when his food stamps come up for renewal, even though not a single thing has changed with his situation, the county finds a way to screw it up and we have to call them and get it straightened out. Imagine what happens to people who don't have friends that can help them navigate the system.
The root of the problem is not that helping the less privileged is a bad thing; it's that the state is the worst possible tool for the job.
> I get really frustrated with libertarian types that would dismantle useful state programs before we've got something to replace them.
We do have something to replace them: private charity. Anyone can found a nonprofit charity organization to help the less privileged. And they would do a much better job of it than the state does. The fact that the state is doing it at all hurts the actual ability to help people, because the people who would actually do a good job at it are thinking that the state is already taking care of it so they don't have to. Which means that there are actually more people who need help that are not getting it, than there would be if the state were simply out of the business altogether and everybody knew that it was up to them, as private individuals and private charities, to do it.
