Ships are a lot bigger and we expect a lot more reliability from them than we did in the wind-only era. This makes tugs necessary to enable safe maneuvering in harbor.

Bigger and containerization have the effect of making shipping cheaper on a per-unit basis, which is why they're used.

Yes but producing things locally improves resilience and allows for decentralization. Large container shipping is a feature of free market capitalism and highly centralized industries. In a decentralized economy there wouldn't be anywhere near as much demand for container shipping.
