My questions is that ' is there any possibility that some point in time in future BTC community might decide something which can retrieve this lost BTCs?
What this can lead to is hardfork that will lead to the creation of an altcoin, just like bitcoin cash.
If the lost bitcoin are to be recreated, who will be the owner? The lost coins are lost but not lost in value, the value of the lost coin will be added to the ones that are not lost as the circulatory supply is reduced. So, why creating it again, even no one knows the coins that have lost, because a coin is not transferred over 50 years does not mean it is lost.
The more the circulatory supply is reducing the more the increase in price as the coin become more limited in supply and will become more valuable.
Protect your wallet, seed phrase, private key and coins so not to be a victim of a lost coin.
