Let's just cherry pick on DeFi. DeFi had something around 10% of its entire TVL lost last year to hacks and scams. I guarantee you that 10% of the entire 'TVL' of PayPal wasn't lost to hacks and scams.
PayPal has almost 79B in assets. Pretty sure they didn't lose 8B to hacks last year.
The fundamental character of crypto - a market where police and regulators look the other way, but money moves freely - whose biggest rocket ride to fame came from Silk Road - is perfectly suited to attract crime and criminality. Without crypto nobody would even remember ransomware because you can't send millions of dollars in Starbucks gift cards.
This is its niche, like it or not. Because if you're not trying to do crime, classical finance is faster, cheaper and safer.
