DRM is mostly legal instrument. If you want to be able to sue people based on circumventing protections, courts need to consider your "content protection" "effective", which essentially means that it takes more than five minutes to circumvent. It also means that, since we're now talking about DRM that'll be protected by patents, copyright and obscurity/NDAs, that these DRM mechanisms centralize power to the owners of the DRM. This can then be easily leveraged to control and restrict e.g. the features playback devices may have.
