I spent a few years travelling 90 minutes each way to work, now I've reduced that to about an hour each way.

My gf on the other hand works from home 3 days a week, but there is no separation. She'll 'finish' at later hours, and continue talking to clients through the night, weekends, vacations. There is no escape.

For me, I walk away at 5pm and there could be a monkey tearing up my desk and I'll not give the tiniest shit until I clock in the next day.

Can't put a price on that separation, imo.
