The message I get from posts like these: "I am entitled to watch show X right now. If the owner of show X won't sell it to me instantly, then I have the right to pirate it." Is there money to be made here? Sure. I might even say that companies who don't offer popular shows on demand are making a dumb move.

You aren't taking it. You are copying it. The only reason not to be allowed to copy it is if it damages the copyright owner.
But since the product has zero economic value to the owner from you (they refuse to sell it to you), you are not causing them any damage, and therefor you can not make any argument about why it's wrong. (i.e. it makes no difference to the owner whether you copied it or not.)
One of the criteria for fair use is "the effect of the use upon the potential market for or value of the copyrighted work".
And if you also include "the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes" you have met 2 out of 4 of the criteria for fair use, so you could make a strong argument that it's actually fully legal.
