Your original point about Google's geographically restrictions is technically wrong. It's not based on your geolocation but on the simcard inside the phone. If have a simcard from the USA then putting it inside an Android phone gives you access to the USA store even while in Thailand—you can still download over WiFi.
Moreover Android's system solves the problem stated in the original article i.e. move to a new country and Google switches over to that country's store. Move to another and Google switches again. All your apps already downloaded continue to work. All apps purchased can be redownloaded if they aren't restricted in the new country. There is no need to have separate Google Play accounts for different countries or merge accounts.
I have one Google Play account. I have four iTunes accounts (USA, Canada, UK and Japan). Android gets it right imo.
