Why is it that all of the solutions to Bitcoin's "problems" sound exactly like the Bitcoin whitepaper?

From Cashu website:

"WHAT'S CASHU

Digital payments should be as natural as handing over cash in person. Cashu brings simplicity back to online payments."

From Bitcoin whitepaper:

"Abstract

A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution."

Bitcoin has become a platform for 2nd layer grifters.
