it seems very reasonable to choose the "send one person first" option
It's very reasonable when you are looking for a better place to live. It's not very reasonable when you are in the situation of a bona fide refugee -- the risks of staying are too high, so you run.
Beides, I think in practice the percentage of those who could not "find somewhere to stay" and had to return is much, much less than 50%. Once you made it to Europe, you're golden.

The entire point of my comment was to sketch a situation in which it might be reasonable for a bona fide refugee. If you think it's an implausible situation or that my analysis of the situation is wrong, fair enough, but it's a bit off just to object on general principles as if I hadn't just given what is intended to be a counterexample.
