One thing is to set embassies that can give whatever information required by any citizen in the world, another is to make nations responsible for every person that comes into the nation. Best way is a no borders no bureaucracy way. In European Union if I want to be assisted in an health facility of another country with the same privileges as in my own country all I have to do is go to an health center and request a form for that. It's the citizen himself that has to go through paperwork and submit things but you don't need anything else, not even passport, all I need is my ID from my own country. If there's laws of security in traveling that people need to know about I'm sure they're already supplied by airlines or embassies if anybody requests, otherwise they should, as they are in real world. Any other laws that exist in a country needs to be the responsibility of the person that travels. I know I have to drive on the "wrong" side of the road in GB, also that only 2 countries in the EU are laid back about possessing drugs (not that I'd possess them, I don't consume). I also know that in the US you need insurance to drive (which is a bummer).
This bill also sets things in ways that might not be the same or as wished for all nations, like Article 1d and 2b, my nation can contact your nation for information, if it can't, too bad, that person will have to answer the law of my nation anyway.
If you really want security you'd have to set up way more things than what this bill asks. A vista law that affects all nations if we do have borders, standardizing the border control with specific information, such as I have to do when I go to the US, setting rights for travelers in case of health or judicial problems, insuring embassies have their duties to aid foreigners in distress, things like that would make more sense imho.
For instance, setting that any embassy of a WA nation anywhere in the world will be obliged to assist any citizen of a WA nation in any problem they have, even if just by transporting (in case of impossibility or danger of that citizen) to their nation's embassy.
