The problem is realistically, DRM exists to prevent unlawful access and use. Your "right" narrowly avoids the topic by claiming users only should have the right to circumvent that which prohibits access they're legally entitled to.
However, imagine a term of service that only grants access to a website in exchange for viewing ads. (This is the implicit contract of ad-based web viewing from the beginning, but websites aside from some streaming video platforms have not really "enforced" the fact that users pay for content by viewing ads.)

Lets first imagine that the term of service is fully understood by the users. The tracking is explained and understood, the trading of personal data, the auction of targeting advertisement to anyone, the lack of liability in case of malware. In that world it make sense that websites enforce the trade of access in return for all the above.
Until then we have the wild wild west that is online advertisement without regulation, liability or contract between the user and the publisher.
