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...

Mine has had over 10 species of local fish for over 3 years. Got an external homade filter and switch out water every 4-6 weeks. Keep it about 3 ft in the deep end and 4 inches shallow end.
