Yes they can. Taking donations for an iPad each for my four under 13 year olds. Or they can use the family iMac with their own login, in order to learn to use tech creatively, occasionally share iMessages with cousins and family across the ocean in England on their own account, make projects and build a photo library and be able to transition to a device seamlessly later. I just realized that I’ve risen to your trolling. Yet I’m annoyed enough at your answer that a family with many children spend thousands of dollars we simply don’t have for devices for young children just to get an iCloud account when there is a perfectly usable computer siting there... that I’m hitting post anyway.
The point is: Apple should waive this restriction, at least to some degree, especially for children’s accounts.
