Food safety and boiling food to kill bacteria. Why can’t we indefinitely boil food and keep it good forever?

My mom often makes a soup, keeps it in the fridge for over 10 days (it usually is left overnight on a turned off stove or crockpot before the fridge), then boils it and eats it. She insists it’s safe and has zero risk. I find it really gross because even if the bacteria are killed, they had to have made a lot of waste in the 10-15 days the soup sits and grows mold/foul right?!

But she insists its normal and I’m wrong. So can someone explain to me, someone with low biology knowledge, if it’s safe or not…and why she shouldn’t be doing this if she shouldn’t?

Every food safety guide implies you should throw soup out within 3-4 days to prevent getting ill.

Edit: I didn’t mean to be misleading with the words indefinitely either. I guess I should have used periodically boiling. She’ll do it every few days (then leave it out with no heat for at least 12 but sometimes up to 48 before a quick reboil and fridge).

For the fridge part- a fridge keeps food too cold for bacteria to reproduce effectively. It keeps food safe for quite a long time.
