you need to go back and read the conversation so you know what we are talking about.
In a nut shell, I could care less about what an individual says but more in how people react. If the consumer can use XYZ coin ( a very low power consuming POS) and achieve the same function, security and even better speed than High energy consuming POW BTC, then why not use XYZ
Every trader wants profits and their best bet is btc because they know how hard it has become for miners to mine it. They are keeping its price high because of the resources being used to mine it, making a direct correlation between consumption of resources to mine a btc and its present value.
Now, when talking about security, none of the PoS coins in my views can beat the security of btc, please draw me to one which can and I will think of changing my portfolio from btc to that xyz coin. If such a thing would exist, it would have taken over btc already. Every node validates a transaction making it more difficult for a hacker to break the chain and move that transaction his way. I agree that the speed of btc may be less if compared to so many altcoins there, but we still use it because we know the value it has given to crypto and is still adding it with its mining. And when all the alts (your PoS coins included) are created to provide the nearly same functions that btc gives, I would twist and turn your question and ask you: why not to use btc over them when they are only copying what btc did years ago? In the end, it is all about choosing the right coin and if btc is my right coin, I will go for it and you may go for your PoS coin.
In Bitcoin Security ,
Is it the High PoW Hash rate that keep it secure
oris it the Fact that the top 4 mining pool operators have so far agreed not to collude their over 51%
and double spend or other shenanigans.
And yes, we all know miners can point their miners at different pools,
but the point is , those 4 pool operators only need 3 to 6 confirmations to double-spend, where it can't be undone
so ~1 hour for them to totally destroy bitcoin security as you know it.
Odds are the miners would not even find out for 4 to 6 hours after it happened.

However a PoS coin such as Cardano has 2,523 Active Pools.
So for me , I'll sleep better with Cardano security ,not to mention it's energy efficiency means no government has to ban it.
Bitcoin only offers ~7 transactions per second, Cardano offers 256 transactions per second.

seconds To me Cardano wins hands down, but I also am not following bitcoin like a religion.
The actual tech specs are all that matter to me.
FYI:
Cost for the Bitcoin Pool operators to 51% attack the BTC network is $Zero .
Cost for an outside entity to 51% attack BTC is $612,664, for an hour-long 51% attack.
source:
https://www.jumpstartmag.com/understanding-51-attacks-on-blockchains/Cost for an entity to 51% attack Cardano, is ~$24 Billion US Dollars, for even a short 1 hour attack.
And that is only if buying up the Cardano does not raise the price per coin.
Which it would.
Plus spending ~$24 billion just to destroy the value of that money , is not a wise choice.
I feel safer with Proof of Stake coin Cardano, but that is just me.
