OK, I see what is going on and the person Lex is talking to is using the wrong terminology.

Ethereum isn’t a token. It’s a network. Its super power is programmability.

The network has MANY tokens and one of those tokens is Ether (commonly abbreviated as ETH), and that’s the gas token. It’s used to execute to smart contracts. It’s not scarce, and I don’t know too many people who view it as an investment at this point. You have it to pay for gas (transaction fees).
