There was a Border Force episode, where it showed a backpacker selling his art work door to door getting deported - I truly felt sorry for that dude as I seen countless Aussies on dole, doing substances..
True backpacking is such, working in the fields etc., and finding money to spend on travelling as many countries as possible..
Not everyone can afford package tours and I believe package tourists don't get to cover every country..
At the end of the day, it's not nice to laugh at a person's effort..
