As far as I can that's not actually true; a band uploading a music video 
to YouTube without providing a text alternative violates various 
subsections of WCAG section 1.2, some of which are at level A. The 
synesthesia example violates 1.1 or 1.2 depending on what form the 
content has, although that was far from being the point of the example. 
The other examples do not violate WCAG inasmuch as they were 
deliberately chosen to be non-web examples.

It's interesting that you seem to think the main impediments to 
accessibility of real-world artifacts are physical and economic in 
nature. Taking the case of the bookstore; it would, as you say, be 
trivial to distribute an accessible electronic copy of each text 
alongside the printed copy. Alternatively a DVD containing the audio 
recording of a book could be provided; this would often take up 
considerably less shelf space than the book itself. Reproducing 
everything in braille may be impractical but other options exist. 
Despite this, you seem happy that this be left up to the whim of the 
distributor and, by proxy, the individual publisher. This seems rather 
different from the online case where the prevailing view, at least from 
the accessibility community, seems to be that not providing alternate 
media versions of all creative works is a reprehensible failing of the 
original author.

My impression is that as a society we do not generally expect people to 
shoulder this burden for all the works that they create. I would hazard 
a guess that the underlying reason for this is not due to limitations of 
physical space as you suggest, since these can be overcome. I posit that 
the scarce resource that society needs to conserve is human effort; as I 
said before a requirement to make all creative works universally 
accessible would present a serious barrier to the creation of new works. 
Society seems to have decided that having more creative works available, 
even if some of them are not accessible to everyone, is an acceptable 
trade off. This is rather different to to position that society has 
adopted on similar questions with regard to services (including stores, 
holiday camps, etc. but excluding things like radio stations), which 
generally are required by law to be accessible.
