In some parts of the world, if you meet people and they ask what do you do, and you say, "I do X, I work for Y" they nod and understand. If you say, "I run my business" you are met with serious suspicion, as a possible scam artist. It can impact you real life social network, dating etc. Not only that, online businesses are not guaranteed for life, things changes fast. But career is. You can say I have been a teacher, IT admin, programmer or XYZ for 20 years. Doesn't matter if you changed job once or 30 times.
