That isn't a right, and plainly obviously not true anywhere in the world.

What do you mean by that?

Patents? Copyright? Brands? Standards? Product Safety?

I want to sell you lead toys and asbestos talk powder, what about my rights?

This is a very foolish thing to say.

Here (Canada) our nuclear power plants produce tritium as a byproduct.

This can be used to "boost" nuclear weapons. Should Ontario Hydro be allowed to sell this in the open market? It goes for ~$30,000/gram so Hydro would LOVE to be able to sell it.

What about poisons? They have no real use besides killing others, should they be available in your local walmart?

DDT, should we bring this back?

You see the point?

There is no "right to sell whatever you want" and there never will be one.

You can buy tritium on Amazon here in the US.

And Walmart has dozens of poisons in stock. You should be able to find bromethalin, a neurotoxin, in any one of them.

I'd love to have a glowing vial of tritium and I cannot find them on Amazon. The one site I can find says that it won't ship to the US without proof of an NRC license.

Actually, your comment is foolish. Allowing companies to not sell specialist tools to third party repair persons is not the same as selling weapons grade plutonium.

Is this something you think exists, or something that you're proposing? You're very cryptic.

Then they can start their own country.

Rights come with responsibilities, which are not set in stone. As we learn about the impacts of a certain activity our moral expectations evolve. And so we change the conditions that are required to assert that right.
