Another way is to not do it. The law does not require you to implement crazy DRM schemes, it requires me to not distribute copyrighted work to which I don't own the copyright.
The law doesn't force companies to implement DRM. It's a choice, and as a choice, it can be considered malicious action by customers.
Grocery stores doesn't hire large amount of security people so that every customer would have a security person assigned to them that follows them around and ensures they don't steal anything. They could do it, I don't think any law anywhere prevents them from doing that. But the first one to try it would quickly lose all its customers. If such a practice happened to get ultimately established (e.g. normalized by stores in non-commodity position), I suspect the meatspace equivalent of FSF would be ranting about it too.
Of course, I'd argue most DRM pushes normal people to piracy because the restrictions usually suck. Had they just distributed the content in a more unrestricted way, they'd do more business. But that is a business problem, not a technical one.
