A fire extinguisher can be found for less than 100 USD and is a must-have. A smoke detector is also a bare minimum in my opinion.

In your opinion? You're required to have one where I life
In the USA private homes are not usually required to have them. Rentals, yes, but that's a responsibility of the landlord.
I've been to some places where smoke detectors aren't required by law (or places where it is required by law but there isn't anyone to enforce it). It's weird AF.
I apologize if I was unclear in the first message
One of the first projects when we bought our new house was to replace all the smoke alarms with smoke and carbon monoxide alarms and replace or introduce a fire extinguisher everywhere that needed one. It was a little expensive when it all adds up but well worth it.
