I'm not necessarily arguing against you, but "problematic" is too generic a term to be useful. Genocide is "problematic". Having to run to the bathroom every 5 minutes to blow my runny nose is "problematic". What do you actually mean?

You can't own ideas, they got their own life-cycle.

Right, but I do think you can "own" (by which I mean our societally-mediated legal definition of ownership in the anglosphere) specific sequences of text or at least the right to copy them?

Responding to sibling comment: We need some clarification here: are we speaking about just ideas in the abstract sense, or ideas that have been fleshed out i.e "materialized"

If the latter, there are many laws that say you can own an idea, provided it exists somewhere.
