"WOW I need to send some money". Enter: PayPal, Venmo, Trust Wise, and any number of others.
There are plenty of ways to gamble and speculate without touching blockchain if that's your thing. What's amazing is even a mafia bookie or the shadiest of casinos won't pull a Celsius on you.
Don't trust the government? With blockchain you're expected to completely trust yourself and any number of shady characters in the blockchain space. Clicked the wrong link and your wallet got hacked? Sorry. Forget your seed/passphrase? Sorry. Some defi exchange with a buggy smart contract (as if there are any that don't have bugs)? Sorry. Picked the wrong exchange and the people behind it faked their own death and disappeared with your money? Sorry. The list goes on and on.
Other than the absolute worst and shadiest governments in the world do you trust these factors and actors more? Does anyone else?
I sure did, and I wasn't alone. I remember thinking the existing search engines were trash long before google came around. The market was starving for a search engine that was user-focused and not 200% bought and paid for by marketers.
Similarly, no one will ever say "WOW I need blockchain in my life right now" but they might say "WOW I need to send some money" or "WOW some of my friends are making their money work for them maybe I too should do some speculating" or "WOW I distrust the government's control over the financial system" and blockchain will occasionally prove to scratch that itch.
