I think what it comes down to, is that games like this shouldn't really be bought. They should be experienced a single time - like a rental - but owning them outright is excessive. If I could pay for a Netflix-like service, where I can experience 5-10 handpicked indies like this a month - I'd sign up in a heartbeat.
Nobody makes games like Gone Home. And if you want the market to go in a direction where nobody is allowed to make any money producing a title like Gone Home, then developers will continue to not make games of that ilk.
Netflix has almost no first-run content. Movies often do not go up until years after they were released in theatres and have made a ton of money from the box office and DVD sales and HBO.
If you don't want to pay $7-10 per hour of content, then don't go to a movie or buy a game on the day it's released. Let the creators take in as much as they can at a premium price, then buy it later when it's marked down or put in a bundle.
