You're confusing "asking people for something" with "talking to people."

Nobody wants randos coming up to them and asking for something.

Most people would be less lonely if everyone had more practice at making non-transactional conversation.

Actively avoiding conversation still qualifies as "weirdo" behavior to most people.

"Someday - and that day may never come" - they will be asking for something. Now you are on talking terms and it will be harder to refuse the ask, compared to the request of a complete stranger.
