There certainly are benefits.
One benefit is escaping the every day pressures of surrounding friends and family. It's not that they are not liked and loved, but they require a very significant overhead, between the fun times and the problem times. While on the road there little problems and repetitive fun with familiar others are not part of your everyday.
If you're not an extended traveler you may find the though bordering on the evil or selfish.
It doesn't prevent us from giving a fair amount of travel time to others, generally a more intense time. We have spent tow months as part of the lives of our Seattle grandchildren, or taken them to Alaska for a month. A month in Alaska can be more meaningful than 30 birthday parties.
Attacking no one..just a thought about some road benefits.
