Maybe this is getting too philosophical (was: Debian adds LoongArch support)

Not quite -- "Life, Liberty, and the pursuit of Happiness" is in the US declaration of independence.

The actual constitution doesn't state anything about rights, at least not until the bill of rights that comprised the first ten adopted amendments.

But even the bill of rights just says "No person shall [...] be deprived of life, liberty, or property, without due process of law;"

Happiness (or the pursuit thereof) is conspicuously absent.
