Other than it being unconstitutional (that pesky little document that is supposed to keep gov in check) I think it all comes down to one decision. Do you want the federal government dictating to you what you must buy...who you must buy it from...and fine you if you do not. I say no...others I am sure will love being told what to buy and where to buy it. All comes down to your beliefs in who should make decisions in your life...you or your government.
Once you open up this Pandora's box...it will be only the beginning of them making decisions for you.
