Blockchains are, by design, incredibly inefficient. I'm not talking about mining; take storage as an example. The consensus may be distributed, but the data is purely redundant. The majority of nodes in the network will have to hold a complete copy of the entire chain. If Web3 takes off, it will become more difficult (read: expensive) to operate a node in the network -- doesn't that seem backwards? I haven't seen a protocol address this in a meaningful way, it seems to be shrugged off as a bridge to be crossed at a later date. Storage is cheap! But I don't see how these systems could scale to be truly impactful while remaining so inefficient.
