Over Ethereum there are completely automated exchanges (think Nasdaq), lending, escrow, stablecoins, zero-knowledge proof verifiers, games, payments...
Blockchains are designed to meet the most extreme requirements of availability, censorship-resistance and cost of attack. They achieve them by exploring the extremes of replication of the solution space of distributed systems. For example, Ethereum runs on a Raspberry Pi, and every node runs the exact same things. Therefore how fast it goes is limited to the slowest node you want to make able to run the blockchain.
But, what you are dismissing as simple batch processing are the application of very novel techniques (novel as in math was invented in the last 5 years to make them possible) that allow to externalize most of the heavy computation outside the blockchain and delegate to the blockchain the verification of a proof. Therefore allowing to inherit the security properties of the blockchain but achieving much higher scalability.
Ethereum settles nowadays 200 bitcoin equivalent transactions per second. And is targeting to scale to 1-10M transactions per second by 2030.

All of those "oh my god complex things" on Ethereum are a variation of "look up a single number in one account, look up a second number in the other account, add or subtract two numbers".
Even doing a KYC + proper credit check on a client will cripple Ethereum.

So, batching. But with an extremely complex processing that you trust devs implemented correctly.

No one cares about "equivalent transactions" to be honest. People care about actual things being handled by actual transactions they engage in.
