I'm a libertarian too, I don't like unnecessary government intervention, and I think this case is no different to any other "save them from themselves" kind of policy.
If people truly want to buy equipment that saves cost by removing physical switches, there's no reason the government should be stopping them.
If people want to engage in open and free trade and make an informed decision, I'm all for it.
The problem here is that you are effectively making an open-ended, infinite choice. You have no idea what that information could be used for. You might have grandkids who could suffer. There's no reasonable exchange here that makes sense for the individual.
So I just don't see how a free and informed choice could be made, since the person making the choice has no idea what they are choosing. This is a similar question to asking if people have the right to sell themselves into chattel slavery. I think the answer in that case is also "no". Indentured servitude, perhaps -- but that's a discussion for another day.
