difficult -- drawing those lines is hard. If everything was black and white, this would be easy - we could say, duh, of course it's fine to travel, but not to play. But it's just not that simple - it's a compromise, it's a give and take, it necessarily requires doing some things that (at least arguably) fall on the "un-holy" side, in order to achieve some other goals. That's hard stuff.
Re: not worrying/debating about it - this is a message board. It's fair to discuss whether the line that is being drawn (the compromise that has been chosen) is appropriate or not, whether we agree with it or disagree with it, etc... that's what message boards are for.
