But this is just a threshold issue. What does the difference in cost have to be for you to rent vs buy.
Let's say it's $60 to buy a season of a show on hard media that you can watch as many times you want and yes, you own something that will collect dust for a life time. Perhaps you can resell it, but that just means your initial cost was lower and you in a sense rented it for the difference in price for that time period.
Now if the cost to rent is say $20 for a season would that be worth hassle free experience of the content? How about $10, $5? At some threshold the value vs cost starts to make sense.
