Kind of a random, uninformed thought, but I wonder if there would be a benefit to some blockchain system using a mix of POW and POS? Like having a separate token for each consensus method?

I'm not exactly sure if I understand your comment or what you are getting at, however there is already a transition to PoS (staking) over PoW (mining). Eventually mining will be a dead scene and will be considered obsolete. Staking uses 99% less energy, and is where the industry is heading.
Ethereum will reduce its energy consumption by 99.95% following its transition to proof-of-stake and blockchain merge.

If there is potential money to be made, crypto will thrive. I don't believe there will ever be any hammer that comes down on crypto, other than further clarifying the tax liabilities and enforcing those laws.
As mentioned before, the power consumption is FUD. The naysayers love to compare Bitcoin's transactions per second to other methods, but that's not a fair comparison. That would be like comparing the quality of two seats while one is literally a seat, and the other one is a full airplane.
Bitcoin doesn't just offer transactions. It replaces banks (including buildings, ATMs, transport of money in trucks etc), payment intermediaries, payment networks, security software and protocols, servers... It basically makes the whole traditional financial system obsolete in a way. No wonder so much FUD is being spread about it. The ones that did very well in the current broken parasitic system have an incentive to try and break it. And look what just dropped;
Leaving this here also, again;

Whether PoS or PoW is better is not so simple. With PoW, the miners are incentivized to sell at least part their coins for a profit. This increases the wealth distribution, because it is financially impractical and unreasonable to hold everything that is mined. If they want to keep the advantage in the whole space, they need to keep expanding and doing the additional work as well.
With PoS, stakers are incentivized to hold it, and anyone that had more coins at the start is pretty much guaranteed to gain more than everyone else afterwards. There is little incentive to do anything other than holding the coin. No expansion, no distribution, no cost to hold or produce new coins. There is no disadvantage to hoarding, and that is quite a big flaw if crypto's aim is to be decentralized.
