> The water it's made from is boiled eliminating any funkiness, and by the end the alcohol it has in it makes it inhospitable to said funkiness
Except ale produced at home goes bad very fast. In the middle ages it basically had to be consumed on premise/same village and couldn’t be transported anywhere. Also it’s a wonderful and nutritious environment for bacteria to spread. The alcohol content is generally much too low to affect this.
But back to beer, by the late Midages it had already even started to become a significant international trade good in many places, which wouldn't really work if it was just spoiling. Similarly in the Age of Sail (and probably before) it was also a typical ration on board ships, which again doesn't really work without very substantial longevity.

The other post I cannot find right now was much more detailed than the faq links, but I can’t seem to find it again using HN search
Not mine. Medieval ale didn’t have any hops in it (it didn’t become widespread until the 1400/1500s in some countries like England) so its shelf life was shorter

Why do you think so?
You can also find the preservation of a certain type of mentality all the way to modern times. In many places, including Russia and Sweden at the minimum, many alcoholic beverages (like kvass) are not age restricted at all, because they're not considered an alcoholic drink in the normal connotation of such. Here's [2] also a nice quote from an 18th century book: "For the drink of the more robust children water is preferable, and for the weaker ones, small beer."
There is overwhelming evidence for beer as a normal staple throughout most of all history, and for people of all ages and stations.
