But in the context of office vs home, if the OP is basically saying "I like my free commute" then you have to remove cost & time from the "pro" list for WFH.

I used to like reading on the train as time for myself but it didn't balance out the other stress & cost of commuting.

If Transport for London said that trains would be free at the point of use & actually put on enough service that most people got a seat I'd definitely consider the office more favourably again
