So if ready alternatives didn’t exist, sure PoW is wasteful but has no alternative... but we have an alternative. If there were alternatives to running a social media platform that didn’t spend energy we should also back that option.

Assuming you are talking about PoS systems, I think they are very promising but it's still not obvious that they can achieve the same risk profile as PoW systems. I think they are worthy of further research and I am excited to see how Eth 2.0 works in practice, but I don't think we understand the economic nature of cryptocurrencies well enough to definitively say that it can completely replace Bitcoin.
As for the carbon side of the issue, that isn't something which is specific to cryptocurrencies or any other kind of energy usage. I support carbon taxes and import taxes on CO2-producing goods/services, including cryptocurrency services, and I am certain that many cryptocurrency believers feel the same way.
