Contingent staking, is it the future of POS chains or something we should all fight against?

The ADA community is divided, Charles is discombobulated and the argument remains - Is Contingent staking the future of ADA and other POS crypto currencies?

The simple definition of what contingent staking means is basically giving the staking pool operator the choice to implement some sort of conditions that would allow them to reject certain delegators that don't meet these conditions.

examples:

• Only US citizens can delegate their ADA to us - users must prove they are from the US
• Only non US citizens can delegate their ADA to us - users must prove they are outside of the US
• ​

Now I want to clarify that this at least at the moment seem like something that would be required by all staking pool operators but it would give them the option if they wanted to implement it. Delegators would also have the option to simply switch to a different staking pool that is not using contingent staking if they wanted to avoid it.

The argument for Contingent Staking:

This will allow staking pool operators to chose exactly who they allow to delegate with them and help them meet any local regulations where they are located, this will ensure that the staking pool operators can keep running instead of having to shut down due to fear of operating illegally.

The argument against Contingent staking:

This is going against the crypto ethos and leading to more centralization instead of against it. It's a slippery slope that will only lead to more changes in the future to keep appeasing regulators.

So far this is only being discussed in the Cardano chain but it is possible that this could be implemented in other POS chains, Do you feel like this is something that is required for crypto to continue to move forward or something that we should do our best to avoid?
