I would happily support DRM that actually cared about customers' rights. I want the guarantee that, like physical media, DRM-protected content will be available in the far future. Blu-ray already fails this test, and I only purchase Blu-rays to strip the DRM and save a long-term format. I want the ability to gift, loan, or sell any media that I possess the rights to. I don't want to possess merely a ticket which grants me admittance to content for a limited time, under limited conditions, subject to the dissolution of whatever producer, licencor, or operator manages the DRM scheme.
Because piracy has absolutely no effect on 99% of customers I am fairly certain that what content producers/licencors truly fear is "casual piracy" and fair use like loans and libraries where market forces drive the resale cost of digital media down to its natural price in the free market.
It's perfectly natural to resist inferior DRM schemes by refusing to make them standard. If you want me to support an open DRM standard then it needs to be capability based with normal customers like you or me represented as first class owners of those capabilities and implement a durable scheme for transfer of those capabilities into the indefinite future.
For example, consider a ownership-based scheme where producers issue N digitally-signed capabilities to a particular copyrighted work and sell them to customers on an electronic marketplace. Bitcoin has proven that it's possible to maintain a globally consistent transaction ledger of ownership of individual tokens, and a much cheaper implementation could maintain ownership and facilitate programmatic transfer of capabilities to digital works (to support sales, gifts, and even temporary loans) because the marginal value of acquiring more than one capability to the same work is zero and so there will be little need to spend gigawatts of electricity maintaining the blockchain against adversaries. The copyrighted work doesn't even have to be encrypted. Just make standards-compliant devices/software require current ownership of a capability to use the work. Yes, this is an easily defeated scheme for pirates, but so is every other DRM scheme. At least this respects individual property rights, the first sale doctrine, fair use, and libraries for the vast majority of users.
