1. I have friends outside work, I do not have an urge to socialize with people and potentially interrupting them from doing their job.

2. My manager has better things to do. Being in the office doesn't mean you are being productive. Sometimes you get distracted by noise, or some local office jerk, or some random event... e.g.: in a large company, every day is someone's birthday. Or someone wants to go for a walk and grab coffee...

3. I can live closer to the office and pay as much as twice in rent, or live farther from the office but have a larger place that my family can enjoy more, at the cost of spending more time away from home. If I work remotely, I have up to 2 extra hours every day. I can use that time sleeping, exercising, interacting with my family, cleaning, or do whatever needs to be done that is more useful than spending 2 hours stressing out in a car every day, polluting the atmosphere and congesting road infrastructure, or worrying about being mugged in a train.

4. Trying to escape from your problems won't make the situation better. You still have to go home at the end of the day and deal with your problems.

All that money wasted in a desk/cubicle/office, meeting rooms, cleaning crew, security crew, facilities crew... who do you think is paying all that money? your employer is. It's a lot of money that could rather go to something else, like your compensation, or hiring more people so you have less work to do.

If you are an engineer, offices = a lot of resources and effort put into making your life worse.
