I think the problem is that there are different ideas of a good wedding.
Adult, smart clothes, sensible, expensive venue, alcohol, fancy food.
vs
Family, aunts, uncles, cousins, children, basic good food, a bar, venue decorated by the family, catering by family.
Both are great, both have their place, the second is made by having family there, including children. Everyone catching up and children playing. You are far more likely to have family there than friends.
The first is more adult, and frankly boring for children. Much more for friends.
The thing is that not all of us have a family that would get together and have a knees up like that. We recently had a party for my MIL 80th. It was rather like a wedding reception in a lot of ways. It was in the village hall and we all contributed. MIL is one of twelve so there was a huge number of people there, from new borns to people into their 90s. There was an Irish band and we had a smashing time. In that kind of event children to make it, because it’s family.
