The 'real world' stuff naturally happens in the real world, and not on chain. An example - last year I used a lending app to cover some of my taxes for a few months. I deposited asset X that I didn't want to sell at the time, borrowed their bespoke stable coin against it, swapped that for USDC, withdrew the USDC to coinbase, swapped it to USD and put it in my bank account to pay my taxes. When I could pay it back, I basically did the reverse. And at the end of the day because the lending application was offering 'borrow incentives' with their governance token, I ended up slightly ahead in after paying their repayment fee and gas fees. And all this was done with only substantial human counterparty risk when it came to interacting with coinbase. I found that useful and certianly helpful to me in a real world way. But if you only looked on chain it would not look like anything in the real world was happening at all and just lots of virtual bits moving around.
