Every human has a right to enslave three other humans and force them to build a house. When a house is finished they have to be released though to prevent infringing of their own human rights.
I refuse to believe that you actually believe that's how "rights" work when it comes to rights that require the labor of others to provide. Nobody can actually believe this in good faith.
Children have the right to a K-12 education. Do you consider the entire public school system to purely be slaves?
If I go to an emergency room, I have the right to life-saving treatments even if I can't pay. Are the doctors slaves?
No, of course not. They all get paid. They're all free to quit their jobs at any time.
Let's steelman GP's argument, which obviously was hyperbolic. But it's true that positive rights (or entitlements) are always paid for by the labor of others. K-12 public schools are generally majority paid for by local property taxes, and we all know what happens if you stop paying property taxes.
The average American worker already pays close to quarter of their earnings in labor-related taxes[0], which doesn't include property tax, sales tax, or any other kind of tax that people pay. I think we can safely estimate that at least a third of everyone's labor is already spoken for by various layers of government; this lines up with the pre-Covid US government expenditure as a percent of GDP, which was around ~35%[1].
Of course, all of that spending was decided by a democratically-elected government and people more or less buy in to the idea that it is for the common good of the country. But as that spending increases monotonically over time, and as people share fewer things in common with each other (I mean, try putting a 22-year-old college graduate working at a nonprofit in Brooklyn and a 22-year-old journeyman electrician in Iowa City in the same room), it gets harder and harder to believe in that common good, and you start to wonder why a third of your productive output goes to things you had no direct choice over, and why the people who make those decisions get richer and richer. Half of the top ten richest counties in the country[2] are suburbs of Washington, D.C. Does that make you feel good?
And guess what happens if you try to keep more of your productive output? You go to jail. That's what people mean by "slavery". Or at any rate, this is my attempt at steelmanning that argument.
