That's the main problem with many of the "blockchain" solutions - is that they're just reimplementations of already-existing solutions to problems.

You can run someone else's software and pay for the actual running thereof, it's called installing it on a virtual machine (and things like the AWS Marketplace exist for turn-key solutions). Maybe something "microtransactiony" could happen here - but why would you need a blockchain when AWS can just make "Marketplace for normal people"?

And many of the other solutions provided end up having a central authority, in which case why not just have ... a database? Amusingly enough most crypto exchanges are internally run not on a blockchain but on a database, even though in theory one entirely on a blockchain might be a workable use case.

Huh? Are you not familiar with uniswap? That’s a fully decentralised exchange running on blockchain.

Interesting - I expected there to be one, but I've never heard of it compared to the big-names.

You might not have heard of it but it does significant volume. For example, if you look at the USDC markets and sort by 24-hour volume, you'll see that Uniswap is at the top.

Uniswap is relatively new - started really working last year. There are large numbers of decentralised exchanges now.

Because we tried the whole centralized database thing and it just leads to trillion dollar monopolies built on value extraction of users and open source developers.

They're also federated, but at the cost of being exponentially more expensive to run.
