All human rights are contingent on material situations, except possibly rights that are exercised entirely in your mind. The point of rights is that they are things that we have widely agreed governments will not try to stop you from doing. That doesn't mean that they have to ensure that you have the means to exercise those rights. For example in much of the world (including the US) freedom of movement is a right. If I want to travel from my home in the Pacific Northwest of the US across the country to Florida on the public roads the government cannot simply forbid me from doing so because of my freedom of movement rights. However if I can't afford transportation, or the food and lodging I would need if I tried to walk to Florida, the government does not have to provide some means for me to get to Florida that fits my budget.
