The tequilla example is only if the seller provides all the mixers as part of the $50 purchase. Disney sure as fuck isnt going to give you an LCD if you pay $10 per movie as opposed to $5.
Your "temporal" argument is invalid. Watching the move NOW (once) for $15 includes the services of the theater. Paying $10 in 3 months is the value of the movie at that point in time. $5 is the value of the product in a year. Just like when a 2014 truck is valued today at $50k as opposed to a 2005 truck valued at $25K, goods depreciate in value even if they are unused. The consumer public generally wants what's hot today, and they pay a premium for it. Paying less a year from now is not just aniticipated, it's expected because that product doesnt have the same market value it once had.
Purchasing an aged product, and the value curve associated with that doesnt address this new billing proposal at all.
The challenge of the contect industry is to produce a good that has value, and selling it for what the public is willing to pay. That product is worth X. Not X +/- my personal environmental variables. I dont pay more or less for my print edition of The Lord of the Rings depending on whether I read it in a beautiful quiet park in mid-may under a shadey tree, or while riding a greyhound bus cross-country sitting next to a vomit-stained anarchist named Bulldog who has a bowel disorder.
