Transport is too expensive and that is the only reason. Buy a car or better a van and they are the best two countries in the world to visit. Good roads and a variety of climates.

Yes but expect to sleep in your car or camp on BLM land or park in truck stops. Also always cook your own food bought in grocery stores. Leaves your only expenses gas and food. Travel slowly. It would be tight but certainly doable.

It just make you look dumb. But with modern education I doubt anyone will notice.
