Digital ownership is enforced by the code that’s interpreting the data, so the app publisher is the organization responsible for enforcing property rights. Tokens signed by an app-trusted key solve the problem with almost zero resource cost.

This ensures safety against access and not against copying. Of course I can not copy assets I don't have access to but the same is true for NFTs.
Enforcement of digital rights is actually easier via NFTs than contracts/client apps etc. because NFTs mathematically can prove ownership (courts just have not caught up yet).
As all things, technically, theoretically possible to circumvent, but you can make it exceedingly difficult.
