What is so controversial about requiring a proof of identity to vote?

It makes little sense to me why this is a bad idea, unless someone is misinformed, or hoping to take advantage of the system

It's a requirement for many basic life things; driving, starting a new job, opening a bank account, applying for assistance, purchasing firearms, picking up orders, buying alcohol etc.

Sometimes the things leftists argue for proves to me they want to take advantage and destroy the system 🤷‍♂️
