Do companies that do not have such clauses and provide comparable services exist? If not, customers are not free to refuse to engage even in theory.
If those companies exist, is there any practical way for customers to know which ones they are? If not, customers are not free to refuse to engage in practice.
The only freedom that customers (=citizens) have is to engage into a cartel (=state) to impose their collective interests (=democratic choice) on companies by force (=law).
Companies are then free to refuse to engage with states which have such customer-protective clauses in their laws.
There is not any significant DRM free digital movie marketplace, and the reality is that movies aren't fungible: if I want to watch Strange World or Doctor Who, I'm not going to just instead watch an indie arthouse film that happens to be available without DRM
Media is as (un-) fungible as always. Your complaint sounds a bit like complaining that you can't buy an iPhone that runs Windows. Bundling is a thing in the economy. You can't buy a Porsche with a Tesla engine either.
You can still buy movies on DVDs, which still can't be disabled remotely. DVDs are very digital.
Yes, you can complain that there's no 'significant' movie marketplace without DRM. But you have to complain to and about your fellow consumers: their patronage ultimately decides which suppliers become 'significant'.
