For most jobs, I would say working from home is just fine.

But I've also worked on a trading floor.

The difference is that on the trading floor, every interaction is mutexed. You can talk to one person at a time, or you can shout down one line at a time. Someone comes to your desk and they get nothing until the previous conversation ends.

This works because you're mostly happy to delay whatever longer running projects you have on your desk, like fixing a spreadsheet. And because the information coming in on those conversations is high value, requiring immediate decisions.

Most people are not doing things in this way. If you're deep coding, you especially don't want someone to come and bother you. There's not much value in immediate interruption.
