proof that humans assign infinite value to objects worth nothing on any market
means A small object kept purely because it reminds you of a person, place, or moment, regardless of any actual value.
from A transparent English compound from the 1700s, built the same way as 'makesake' or earlier 'forsake' — it's literally a thing you 'keep' for the 'sake' of remembrance. The 'sake' here is the old Germanic word meaning purpose or cause (related to the 'sake' in 'for goodness' sake'), once tied to legal disputes and 'matters,' which softened over centuries into the gentle sense of 'on behalf of' or 'for the benefit of.' So a keepsake is, quite plainly, something kept for the sake of memory.
