You could say the same thing about electricity infrastructure, pretty well established and unlikely to increase in cost drastically. Except with electricity, the likelihood of supply running out is a lot lower because it has a diverse set of generation options, which includes natural gas. On top of that, you can generate your own electricity at home and store it in batteries (obviously, only if you have a roof you own), and the cost of doing that has only been decreasing.
