That's what I said. I'm not disputing it- I'm saying it is as much or little a "commercial activity" as other things that body autonomy rights are associated with.

I didn't say that Roe was perfectly in line with other body autonomy arguments, I simply pointed out that it was analogous. That the Court chose to make viability the demarcation line was a matter of pragmatism. It doesn't mean it's legally perfect.
