I totally get this. As one who works in a coworking space I have to fend off people all day. I love to talk, but not when I'm trying to write code. Some people don't realize that headphones are the universal sign of "I'm busy".
Unfortunately this is reality. Happened to me on my first company. I'm hoping to get my current startup cashflow positive before a series A so I can get a revolver instead. My previous company was user-based so it was equity or nothing
