I think we're talking about different things. I was responding under the assumption the commenter wanted to build their own market for trading inflation bets. If someone already did the work to accept money, make the market, and handle payouts then great, leverage that. That betting market exists because enough people wanted to bet on inflation prior to blockchains existing. However, there will be new things in the future that people want to bet on, and those new markets will be easiest implemented on a blockchain. Just a for instance, I can create a betting market based on how many times my dog licks her butt during the day very easily on the blockchain. How can I do that using traditional means?
