I try to live by the rule of I would rather be alive than dead. Being “right” is no consolation when you’re in a hospital bed dying.
The same goes for cars and especially bikers. You may be right, but being right doesn’t stop the giant SUV next to you from flattening you.
I think you’re misreading it. In the same way as there are people that need to ride on planes (for example for their job, or to move to where they have a job, etc), there are people that need to use social media.
For example, if you own an online store you really need to have a social media presence. Same if you are an artist, and live off of commissions. I’m sure there are plenty more examples.
