Smart contracts that cost money to run on a virtual machine with less power than a Raspberry Pi. In order to access a DApp someone needs to buy into some cryptocurrency, providing some early holder the ability to cash out. The DApp user also has to trust that the smart contract doesn't have a stupid bug that will drain their wallet. Oh and thanks to the low transaction rate of a blockchain that DApp might never execute or have a flash crash type spike in cost.

It's a bunch of rent seeking bullshit on top of what could just be a web API. Storage on a blockchain is stupid expensive so there's oracles everywhere pointing to off-chain resources with zero guarantee of availability.

Blockchains aren't adding any value. They're only extracting rent and adding friction.
