Well, for one thing only _one_ of you needs to commute.
Secondly, you can work towards a situation where you don't have that commute, or it's cheap / clean / easy / you don't lose all the time. Spoiler: live on a trainline or buy a bicycle.
Third, I don't believe this is the main reason for commuting. I think it's because people want to live in one place and work in another, which is usually a bad idea - especially for the environment. It irks me when I choose to live reasonably close to work so I don't need to burn fossil fuels to get there, and then people driving their cars to and from some village complain about their commute whilst I have to suffer the air pollution from their vehicles.
I totally get that for some transitional periods a long commute may be required, but I don't know a single person who couldn't make their commute a 20min walk or by public transport if they moved or switched jobs.

do you suggest moving every time you change jobs? I suppose that can be done as a single person or a couple, but moving homes every 4-6 years with children who have to change schools, etc is (I'm sorry) an insane proposition.

Does "commuting" only mean "driving in a privately owned car" where you are based? I'd consider travelling by rail, bus or bicycle to also be commuting.
Depends, often commuting is seen as this long, arduous thing to get to work. When I was going to the office, it was a 15 minute bike ride along canals. Technically a commute, but it doesn't feel like it, and it doesn't take a significant amount of my day. Really, it's a nice small amount of being outside and getting a little exercise and was kinda relaxing, so a net positive.
