How many atmospheres of pressure do you live under such that 175° isn't boiling!

Water boils at 212.

Not at 0.4659 atmospheres. Our friend here is somewhere in the Andes mountains, probably.

It boils at 212 for those who are not using the freedom unit

technically its boiling at 212 for F and C

Not quite ... liquid water can reach 212°C as long as there's at least 20 atmospheres of additional pressure on it.

At standard atmosphere though, adding more energy just speeds the vaporization. This makes water useful for controlling cooking - as long as liquid water exists in a pan, the temperature of the pan can't exceed the boiling temperature at your elevation.

There's a method of cooking bacon that submerges it in a little water. Bacon undergoes the maillard reaction (browning) at [a fast rate around] 300°F. As long as there is water in the pan, browning of the bacon will not occur. The fat, however, renders out at 140°F. So this method uses water to provide the energy to render out the fat safely delaying the maillard reaction until the water has all evaporated. The pan will then increase over ≈212°F very quickly, so best to be careful not to burn it.

Respectfully as you're obviously big on the physics, you're wrong about the maillard reaction. Similar to pasteurization this can occur at lower temperatures over longer time, sous vide black garlic is a good example of this.

That's true - it can occur at lower temperatures, but there is a practical minimum temperature is there not? Is it lower than the boiling point of water at 1atm or does the explanation still hold true in the abstract?

The minimum for practical purposes is 60c or 140f, it will take 3 months to "cook" garlic at this temperature, but the result is pure black garlic, not burnt at all, but perfectly sticky sweet.

That definitely sounds like it has a name - but I wouldn't call a 90 day cook time practical for most people 😄

If you have a sous vide it's set and forget. "Black garlic" is the name, the cooking method is just called ageing, as it is basically accelerated ageing, pasteurization kinda covers this too.
