Can someone explain to me in simple terms why BTC requires proof of work and can’t do exclusively proof of stake?

I’m a big proponent that Bitcoin != Crypto, and I’m not an ETH gal, but just learned about ETH’s shift to proof of stake and I want to understand why that doesn’t work for BTC.

Apologies in advance if this is a dumb question. #plebchain
