Much like food or medical care: fundamental rights can never depend on the work of other people. Otherwise you can demand that work, which imposes on their rights.
It’s enshrined explicitly as such in a variety of UN documents and EU laws and instruments.
I wish more of my fellow Americans had a better idea of what fundamental rights the US has chosen not integrate into domestic law over the past 8 or so decades.
Which won't happen until it has an adult president, but that's a different story.
It is the government’s responsibility to ensure the people who provide those services are hired and paid. Nobody is demanding anyone to work for free or to be forced to work on something they don’t want.
At some point, we might get there and mechanisms to compel society to work enough so that society doesn’t collapse will be considered some sort of civic duty.
So public defenders and public school teachers aren't a thing? Jury duty can't be compelled? Conscription like in WWII?
Something being a "right" doesn't mean it's a magical force that overrides all others. Rights are always in tension with other rights. A society deciding something is a "right" is a statement about priorities and values.
On the medical care example, most countries have something like the US's EMTALA -- not a Constitutional right but but a de facto "right to medical care" in emergency rooms and some other carve-outs.
But the fundamental right to medical care this codifies doesn't just override all other things. You'll get rightfully and legally-correctly turned away from an ER if you are extremely violent and belligerent, and cannot be reasonably stabilized enough for everyone else in the ER to be safe. If you're in a remote area and need a airlift, but the weather conditions are not reasonably safe for the only helicopter crew available -- as determined by themselves -- then they're not obligated to rescue you, either morally or legally.
Is 2nd amendment forcing anyone to make guns? Is US hiding population of enslaved workers that are forced to dig up metal, work it, make guns and sell them?
The most cruel part is that a lot of people work on things that result in no meaningful benefit for society.
