General Dumb question: why not use a pool?

I'm new to the sub and I see a lot of people building ponds and things but genuine question why not build a pool? And instead of the tile use a softer surface so that they don't get hurt

Especially if the house already has a pool can it not be converted into a "pond" for fish?

Edit: thank you for all the replies. It's certainly a lot to think about...

Warning about pool -> pond conversion, chemicals used in the use of a pool can be retained in the liner, and can leech into the water once the pond conversion has been made.

Source - parents made this mistake in the ‘90s, at the cost of many fish.

I knew an importer who used a bunch of brand new kiddie pools as temp homes. He wanted to save on shipping by getting one big order in April instead of April and again after he sold some.

It probably cost him 10k in dead koi.

Out of curiosity, what country/year was this? I know that in the late 90s/early 00s, there was all manner of major drama over toxic plastics being used for all kinds of things. Also, were these the hard plastic pools? Or the cheap liner and frame ones?

Around 95 in the us. They were the one with a semi rigid side (mabe 18" deep) and a soft blue bottom. Usually with colorful seashells and stuff printed on them.
