I think in this case they're worried less about terrorists (who can be excluded on other grounds) and more about mass immigration in general. Simply requiring that you say you have a business plan is equivalent to having no requirements, since anyone can say that.

I'm pretty pro-immigration in general, but wouldn't it be more direct to just greatly increase the immigration quotas, rather than making people go through the charade of pretending to have a business plan? Either that, or if you want to insist that it be a real business plan and not a charade, you need someone to vet them.
