The so-called 'bricks and mortar' shopping industry has dug itself a huge hole in much the same way that music companies have.
The industry built a certain structure to exploit the conditions that existed pre-Internet shopping. It revolved around the various links in the chain being gate-keepers, using restrictions and inflexibility as a means to dictate terms - restricting competition and thereby allowing them to keep prices artificially high.
It's unnecessarily wasteful and results in higher prices for consumers. But, the conditions were such that customers were forced to accept it.
Internet shopping has allowed individuals to bypass the deliberate restrictions and anti-competitive behaviours of those gatekeepers but now those gatekeepers are complaining that they are being hard done by.
What we see emerging, though, are those same restrictions being applied through the online shopping system with certain vendors preventing online store overseas selling their products to Australian customers, thus (again) artificially restricting the way consumers can purchase goods.
Competition trims fat and (hopefully) makes things more efficient. The old structure deliberately restricted competition and those responsible grew very fat indeed. Now (too continue the metaphor,) they are too heavy to compete in the newer, lighter environment of internet retail so they are trying to hobble their competition rather than, well, compete.
