Automated signatures work decently when the process is smooth. XCode integrates with your Apple ID to sign apps. Letsencrypt works for signing TLS certificates. HDCP works silently even for typical users.

I don't support HDCP or DVD-region-lock but they worked for the copyright owners without inconveniencing the users enough to affect the bottom-line. It's the technical users and hackers among us who have a problem with these.

I'm not looking forward to NFT everywhere for creatives, I'm saying I can see it happen. I don't want to sign every JPEG I edit but if the tools preserve the source signatures, it wouldn't really affect me.

Photoshop has had counterfeit detection system for over a decade. I'm sure Adobe would love to offer Getty + CS Cloud NFT-copyright integration if they can make it work. I'm sure they can come up with a catchy marketing name for it and build an ecosystem to license, edit, and distribute media with detailed tracking of every asset.
