Not to be a dick, but I have read this several times and I literally have no idea what you are asking?
The video you linked to talked about how complex and nuanced building a wall really is. How difficult it would be to not only construct something but also have it be effective.
I took the above comment as the thought process of disregarding the need for results and starting a massive project without even a clear roadmap. Which is exactly what Obamacare is and was.
