Arguments like these don’t work with kids. Let them experience themselves what is best for them. And have spare socks ready in case they change their mind afterwards
Sure, if that's a reasonable option, but letting the kid hurt themselves isn't always practical. Letting the kids find out 'messing with the pot of boiling water is bad' the hard way, as an example, is not what I would consider good parenting.
Ok but wearing shoes is a social construct. People didn't wear shoes for thousands of years before shoes came along and they were just fine and full of blisters.
To some degree that's true. But these days the ground contains more dangerous objects than it used to. Specifically hazardous man-made stuff
If it was just nature and we still mostly had like forest floor and such, then probably for the most part it'd be safe yeah. Well, with the exception of plants or animals that could damage your feet or bite you
