Not really. Proof of Work blockchain is backed up by electricity alone but proof of stake is valued on ownership.

Also there's several other lesser used proofs that can be used to back up the blockchain like proof of history, proof involving influential people, proof of memory using hard drive space, etc...

There are obvious pitfalls with these lesser used proofs but if you stack all proofs together in a blockchain, the blockchain would build more trust and be more secure overall.
