Proof of stake lacks the security properties of proof of work. They are not comparable. PoS is markedly inferior in many respects. Look up e.g. the “grinding” family of attacks.

The proof is in the pudding. The Ethereum beacon chain text s currently securing $14 billion in value and has been running for nearly a year without incident. I can understand the claim that PoS was impractical even a year ago. But given Ethereum 2’s massive success, it’s an untenable claim. If you really think PoS in insecure, don’t bother at arguing it. Just go hack some of your share of that $14 billion.

  “This tail risk event hasn’t happened yet, so it’s nothing to worry about.”

    You're ignoring the tail-risk events of PoW, like an undetected 51% attack, or backdoor in / compromise of the work function.
