This is an incorrect statement. To be blunt, you are lying.
Not every block increase results in a loss of decentralization.
As evidence, we can refer to your favorite Segwit.
Since 2017, after the adoption, the real physical block size has increased, but no one talks about the loss of decentralization. Everyone understands perfectly well that the network will not even notice an increase in the block by the estimated 1.7 times.

Computer bought for the same price:
1. in 2008 copes with a 1mb block
2. in 2017 copes with a block of 2-4 mb.
3. in 2022 will easily cope with a block of 4-8mb.

You can reasonably increase the block without necessarily increasing costs. Nobody wants Bitcoin to break.
Above, we have already given a bunch of information about how much technology has grown. But you choose to ignore them.
And you continue to get moldy arguments from many years ago from the dusty attic.

It seems to me that you are not quite accurate in using the word "real". If we had increased the block size by 2-4 times in 2017, then perhaps we would now have 2-4 times
increase in the number of transactions. And that would definitely be real scaling.
Instead, you are suggesting that we all hope for some other "real scaling". Which in practice can be just an unsuccessful experiment.

I settled more comfortably on the couch. I want to hear from you a cheerful report on how much progress you have achieved in your "real scaling" over the 5 years since 2017.
