"nobody owes you anything" is just an excuse to be selfish
The phrase "nobody owes you anything" is often used to promote personal responsibility, but it most often serves as an excuse for selfishness. While no one is entitled to unlimited time or resources from others, healthy relationships depend on empathy, respect, and mutual care—not just the absence of obligation.
When people use this phrase to dismiss someone's feelings or avoid accountability, it becomes a way to justify indifference, shirking one's responsibilities (often ones they've explicitly agreed to uphold in the past), and sometimes even justifies cruelly mistreating or abandoning others. Friends, family, and communities may not owe each other everything, but they do have shared responsibilities that make trust and cooperation possible. I find it especially hypocritical when people who call for others to be empathetic and make a big deal about how left/liberal they are politically, etc. suddenly deploy this talking point the moment anything is expected of them. These people often mock libertarians but they are effectively strict libertarians in their personal life (and as many of them say, the personal is political).
The truth is that society works because people choose to help one another, even when they aren't strictly legally required to. Many speak of how they feel lonely, and lament the current low trust social climate where people ghost for any and no reason without regard for how the other person will feel. Based on some of the interactions I've had, it seems they imagine themselves as celebrities (or at least local/small scale celebrities due to having a social media following or whatever) whose relationship with others is more as fans than as equals. The truth is, to assume this status is asking a lot of your community. At the very least a baseline of decency and respect in how one communicates with others is owed. If someone doesn't react in kind, it's fair to react accordingly (but be proportional and fair, maybe they were having a bad day).
