I don’t currently use a VPN provider, but when I do, it now won’t be VPNSecure.

You’re free to do whatever you like, but I really can’t imagine cutting myself off of seeing most of the world, simply because of a bunch of theoreticals. I fly fairly often for work and I’ve not even experienced half of those (I’m not even sure what problem you might have with airport limos). Most of those issues are easily avoided anyway, since they are a product of your own planning.
