It strikes me that it would be helpful to focus on how we can improve the visa process for attendees from (predominantly) African and Asian countries rather than trying to find a utopia that has a very relaxed visa policy *and* a palatable government *and* political stability *and* modern infrastructure/transport links *and* is not excessively expensive for most people to get to. It's certainly not helpful t pounce on people for making good-faith suggestions, even if you think the suggestion is ludicrous.
