Decentralization is being achieved but a decentalized internet is another aspect. It's not that we can't achieve a decentalized internet based on blockchain, the authorities wouldn't let it happen. We consider US, the internet operator to be cruel towards privacy, China another superpower is just nightmare.
No authorities would love a decentalized internet.
Your statement is wrong in a sense more so in the U.S even if the government was to not like privacy they would have to accept it as it is a right not a privelage.
You see SEC focusing on the way in which cryptocurrencies raise funds, still cryptocurrencies are allowed into existence because SEC is not the organization who decides if cryptocurrencies can exist or not as they themselves are not securities. Still those who utilize PoS could be through their staking mechanism.
what decentralise are you talking about? the most pool of cryptocurrency have whales. they can crash price of any token if they want.
If he is truly talking about decentralizing the internet, this would not need the use of cryptocurrency it utilizes blockchain and the decentralization it provides.
Again privacy is a right why are tools used to gain anonymization legal? because the government can't decide to strip a users right away this being in the U.S or else serious consequences would be seen from the people.
Many of the statements posted in this thread are wrong, someone just needs to work on the idea and build it and we will see it put to use, many projects are working on steps to achieve such a goal.
