Granted, this was 20 years ago, but I remember taking the Greyhound and people were getting on or off the bus in the middle of nowhere. By nowhere, I mean the nowhere in the literal sense: at the intersection of two highways in the northern Ontario with no other development in sight. Of course, they also serviced the other types of nowhere: the lone gas station or the tiny village.
The author is being somewhat misleading in the sense that this is not the type of bus service that one would use for your weekly commute to that 10 hour shift at the gas station, never mind the three or four times per week that you would need to cover the bills. It may be fine doing errands in town, where the arrival time and departure time don't much matter. It may also be fine for spending a day or two in the city, assuming you have the budget to stay over night.
I'm not saying that the type of lifestyle alluded to is impossible, but it is not going to be the type of lifestyle accessible to young people. Then there is the question about whether they are equipped to live that type of lifestyle.
