That's true, but some people have more accidents than others! If you're the sort of person who drops their phone in water every couple of months then a waterproof phone ends up being a huge cost saving.
I actually killed a Nokia 6303 because the alarm went off and it vibrated off the window sill into a large pan of potatoes I'd just boiled. You just never know what is going to happen.

Also with these things you never buy at the line. You get something that's a couple of ratings higher than what you expect. That allows some margin for error and uncertainty.
The culprit is Steve Jobs' obsession with thin phones. Just thicken the phone and add some gaskets and you are good to go. People put those thin phones in thick cases anyway, so it is fine.
It's not like using a squirt-bottle. Just buy the seal with the repair part, example below.

It's not really about that. It's about being able to play music from your phone in the shower. Or use it in the bathtub. Or take it on a cycling ride while it's raining. Or put it on a bar table without worrying about spilling beer on it. It makes a big difference not to have to treat it like a delicate flower.
But the time it really got hammered was when it was pissing it down in the middle of nowhere in the UK when I was waiting for a train that would never come and I had to try and organise a taxi in an unfamiliar place. That would have killed the Fairphone 5 dead. It was soaked. Everything was soaked.
Edit: I also have a Pixel 7a which is the same.
Ask me how I know.
I went in and got it out.
Actually, I probably don't want to know.
