You have a point but don't forget, a 50% view is equal to a 36" print. My rule of thumb is that if the file looks good at 100% on a retina screen, which is 220 dpi, then I know it'll make a very acceptable 30" print.
My standard fine art print size for sales is a tad over 21" on the long side. This lens is capable of of doing that well with nearly all subjects at nearly all focal lengths. Of course, if the scene is something I really want to print hugely, I will use a prime, or my IQ180 with a Rodenstock on a technical camera... but huge prints don't sell as well - most people don't have the wall space.
I had a couple of 21" prints that sold at an auction last year for £1500 each. They were in editions of 25. A few other images from other people sold at around £7,000 in editions of 5. The math favours smaller prints in larger editions for me but everyone's buyers are different.
Last comment: I treat the D800 and the A7R as 'oversampling devices'. An RX1 file at 100% looks much nicer. But my prints are pretty much always at 200 DPI or higher resolutions so I really mostly care about a 50% view on a 100dpi monitor, or a 100% retina view. For those uses, this zoom shot at 50mm is so close to the 55mm F1.8 that for most subjects I just don't care about the difference!
EDIT: but I should add that I am not much of a 'cropper' - more a slow and deliberate shooter: I treat it as if I were shooting film, trying to get as much right in camera as I can...
