How can we hardfork our way to a more scam secure blockchain?

While thinking about the future potential of Ethereum, one of my main concerns are more sophisticated scams meeting less tech savy users.

The amount of "I was scammed" posts feels already like ATH and numbers confirm this feeling (23% more scammed money in this year compared to last year).

I am especially interested in ideas that could solve the technical side of this issue. The social engineering scams are probably another topic.

What I like to know is how to deal the 'link-clicking' scams. Or the 'upgrade smart contract' scams. How could developers improve user fund protection on Ethereum itself?

Interested in hearing ideas and the feasibility of them getting implemented.
