I don't get the perspective of people who want to have kids and ask the world to accommodate them so that they don't have to make any sacrifices along the way.

Going to an event where you won't have access to your phone is maybe something you can't do while having kids of a certain age. But they'll grow up and then you can again.

It's kind of selfish to ask that no musician have this policy because you want to be able to attend any concert you wish while having young children.
