This is funny, and really speaks to a fundamental issue we have during education as to assigning agency for what amount to"random" events.
OP is presumably educated and intelligent, and the takeaway they had was that bees “are pollinators” which is true with regard to our interest in them, but definitely implies agency that they are intentionally pollinating, which (I am pretty sure) isn’t true.
It feels like the same question that gets asked in a million different ways of “why did XYZ evolve that way when ABCD?” (Because evolution is random and tends toward selecting for energy conservation. Not to “achieve” some specific goal.)
