And who decides what's "reasonable"? You?
The market.
THX recommends a 8.9 feet distance from a 80 inch TV to achieve a 36 degree viewing angle. At that screen size, you can see an improvement over 1080p from a distance starting at 10 feet.
I guess you're the lucky owner of an 80 inch TV then?
But again, let's take a look at the market statistics;

You can see that the average display has stabilized around 46-50 inches. At that size you need to be between 5 - 7.5 feet away from the screen to meet THX standards and a 50 inch display reaches "Retina" quality at 6.5 feet, which is well within that range.
