I think my main point here is that “legal” does not imply moral or acceptable to society, and our understanding of the technical legal status is not a prerequisite for exploring those factors, which may be the thing that changes the legal status in response to the major shift in landscape.
You risk nothing by assuming things are legal until explicitly illegal.
