Did I say it wasn't possible? No, I did not. I didn't even outright say it was impractical, even though it is. I assumed the tone of my writing accurately construed that, but perhaps it did not. I have been supporting my opinion because I'm not sure what to think when I perceive you countering my points and then it looks like you agree with them a paragraph later.
I think this might be just a miscommunication and we're actually both on the same page.
