While we need to do a better job at directing new members towards important information (see here for my suggestion), there will still be the problem of people unwilling/unable to burn the blu-rays and create custom sets. For those people, buying these things may be the only way they get their hands on them. And that’s a big problem.
Any solution not involving money would be quite a hassle, and the best thing I can think of is a system wherein the party requesting the blu-ray would be required to purchase their own blank blu-ray discs and send them in a package containing their copy of the relevant 2011 Blu-ray discs (as proof of purchase) and enough postage for sending it all back.
A dilemma indeed, but for most I believe easy access to the digital copy (mkv, mp4, etc.) would be good enough for most people, but the people who want a proper custom box set is the tricky part.
