I agree with the intent of the article but for what it's worth does not have to be physical. I have digital music and movies that can not be remotely disabled, censored, changed to fit current societies norms. The problem is when the dependency is on servers that belong to someone else or are controlled by someone else. I can self host my own instances of Ampache or just plain old HTTPS with auto-index enabled or SFTP or anything of my choosing. I qualify those as ownership assuming the digital media does not have some embedded code to reference a remote server and anything resembling an embedded license is stripped out. For sure I will hold onto my CD's and DVD's forever. I regret selling off a lot of vinyl.
