The world is not designed for people who move around from country to country.
There are obvious things like power outlets etc. But online services are no better.
For example, Ikea has me registered in the US and now they wont let me register/log in for the AU site because I'm already registered with a 'different franchise'. The online Apple store is still defaulting to US delivery making it very difficult for me to switch. Wells Fargo is charging me foreign transaction fees and I can't easily transfer funds to Australian accounts (for rent) etc, etc. Very painful.
Obviously this is really an edge case with only a small fraction of people that would ever encounter these issues - but I wonder what would happen if global travel and nomad living were easier. Would more people do it?
