Why are so many mundane items age-restricted in this country?

So yesterday I was ID'd at Tesco buying cutlery (knives and forks). I'm aware the law says it's illegal to sell knives to under-18s, but in practice it seems like every supermarket I've been in has asked for ID for all eating utensils and for things like whisks. I also get ID'd just for buying shaving razors (the perks of being babyfaced šŸ˜…). I'm in my mid-20s and I don't think I remember it being this strict when I was a teenager.

This seems quite weird to me because I don't think of these things as necessarily "adult" things like alcohol or tobacco where there's no benefit to kids and teens having access to them. These are basic household supplies and grooming products. Even knives have valid uses other than stabbing people!

The main reason I'm asking this is because my understanding is that it's possible to move out from 16, but how does that work if you're still considered too young to buy basic household supplies? I'm imagining a situation where a 16 year old needs these things but doesn't know anyone old enough to buy them for them. Unlikely, but not impossible.
