Great point. Aside from the energy requirements that also makes you dependent on infrastructure availability. You seem kind of cynical about the tendency to simplify but we have to start somewhere and taking care of your own setup first seems like a good first step. We ought to be mindful of the complexity we're making ourselves dependent on and solving for that in the use cases you mentioned. Most streaming platforms will let you save a local copy, for a start. You can also rip your physical media, or forego using a computer for media consumption altogether (or in permacomputing terms, self-obviate).

But your point stands and from the perspective of permacomputing is indeed a problem.
