You can't just make a statement and follow it up by saying "That isn't arguable." If you do, all you are telling me is that you believe your opinion is infallible.  I could just as easily say that since The Alaska State Fair is a private organization there is no government influence.  And then say "That isn't arguable."  But I won't, because that would be silly.  It is arguable, because neither of us knows.

But I believe you are giving too much credit to the influence of "The Government".  As a private organization they are being influenced by the public they are trying to attract (the same public that influenced The Government, by the way), and for better or for worse, The Fair's target audience will mostly be in favor of this.  And it's not for Nanny State reasons, most likely.  The public, in general, does not care about others hurting themselves.  They just don't enjoy how it effects their experience.  Unfortunately, that's society.
