the purpose of a metal straw is not to be used once then thrown away. sure, if people began throwing away their metal straws after a single use it would be as bad as plastic straws, but that's not why people use metal straws.

That is the purpose, but you need to look at the outcome of what happens to them.

Bioplastic straws are a superior solution.

No, they're not. Bioplastic straws are not any more biodegradable than regular straws. The "bio" part of bioplastic identifies the inputs for the plastic.

Compostable straws can be made of bioplastics, but require high temperatures to biodegrade, meaning generally temperatures not found in nature (outside of volcanic areas).
