Can bitcoin allow people to choose a PoS hard fork?

This would be super cool to give people a choice. Then they could save the babies, puppies, and rainbows!

What, 18 pages about PoS in the other thread wasn't enough?

"Coins" (like Bitcoin) are open source code repositories
and as such do not give permission to "allow people to choose hard forks".

Individuals can choose to fork any code repository
they have access to, at any time, for any reason.

It is allowed. People can fork Bitcoin any time and create another alt. Without users supporting the fork, it will always remain as an alt.

Perhaps a more technical version of this question is about what happens if i'm trying to run a modded version of the bitcoin protocol on the bitcoin network?   Will my node get ignored?  What validation is there in the network?  What parts of the protocol are validated by hard checking and what parts are mere convention?

Since PoS and PoW are two completely different security models, there wouldn't be consensus between them.  The blockchain would also fork.

I see, perhaps my question wasn't well thought out since I don't know a lot about the details of the protocol.   However, I could imagine someone making a bitcoin client that listens in on the network and tries to participate but implements changes in various aspects.  I wonder which parts of the protocol for consensus are validated and which parts arent.  Does this question make sense?

Not really...how can you have a part of the consensus mechanism that doesn't validate?

Consensus means everyone has to follow the same rules, otherwise, how can we get the same outcome?

do you really think someone would support the fork?

POS bitcoin is called BitBTC. The market peg allows you to always exchange them for close to 1:1. POS doesn't replace POW, it complements it. A POS network like bitshares can do all the fancy things that bitcoin can't, like smart contracts, fast block times and decentralized exchange. Bitcoin can focus on being a currency.

Nope, I'm just asking a theoretical question for knowledge sake.  Not trying to suggest that  the experiment would be a good idea.

It's already allowed. It's called PPC .

The beauty of open source is that nobody has to allow you do to anything, you can just do it

PoS will never go anywhere. It's a dead discussion.
