Why are aluminum cans cheap and disposable but we can't have cheap aluminum straws?

Whats worse is those arent just aluminum cans....

Soda cans are aluminum cans with a LAYER OF PLASTIC inside. We literally can't get far enough away from plastic. That shit's everywhere.

Solution: We used to have bottling plants everywhere, and the loop was "local city glass bottling-> sold drinks-> return bottle -> sanitize bottle -> repeat". Low waste, no plastic crap, and REUSE (of the 4 R's). But nope, it's cheaper to consume new material and throw it "away" AKA: our children or their children to deal with. Its not like they can vote to stop us.

This begs the question: why do we use straws at all? I'd be happier with a disposable sippable lid. Obviously a paradigm where we are rewarded for using our own containers would be best, but I am constraining to the baby steps that everyone is fond of.
Yeah, maybe aluminum straws wouldn't need to be lined with the same epoxy or polymer that aluminum cans are, since they wouldn't have to contain liquid long enough that oxidation is an issue?
An aluminum straw with the wall thickness of an aluminum can would be pretty flimsy (try cutting the top and bottom off a can).
