Most customers don't know what DRM is, how it works and how/when it fails. It's reasonable for a non-technical person to agree with a solution that claims to prevent piracy because they have no idea how these things work and their trade-offs. They don't mind it because they don't see themselves as pirates given that they just bought the media and are unaware of how the DRM scheme can backfire on them despite not being a pirate. Very few people would agree to DRM if the DRM scheme explicitly had a disclaimer "we can, for any reason, prevent you from playing this in the future even on the same hardware that successfully plays it today".
