Yeah, blockbuster wasn't so bad, other than charging you too much. It was an alright experience to rent movies. What's worst is that now we're convinced that that time is over, when it really came down to mismanagement.
I think a rental place that you go to is still viable, you just have to be more careful with your expenditures, and have more to draw them there. Maybe it would work as part of some unique style of theatre.
As to the post...I think it fell apart a little at the end, but I think it is possible that the blockchain could help us with this, but the companies have to let it happen. That's the worst part.
