Yes, but the overwhelming majority of people have a work schedule. I can’t trade my time at 7PM for $10 unless I want to find a second job.
Maybe get on Uber?
Specific results are tradeable for money. I get paid far too much for what I do most of the time, with small windows of specialized action that justifies the waste. It's sloth and inefficacy (due to an inability to measure efficacy) that makes it look like time for money, when it's largely an accounting trick that is more like a payment schedule than a time-for-money.
