This may, or may not, align with being solutions and advice that benefits the public at large. In fact, it is becoming increasingly clear that things are currently "optimized" strongly enough that squeezing more profit out of the system generally corresponds to finding a sucker to take advantage of--normally the public at large.
Startups and their leaders have a "move fast and break things" attitude that is no big deal when imaginary things like software is involved that becomes a big deal when non-imaginary things like people become impacted.
Stacking 6-high triples storage space, sure. But it doesn't stop container ships from running back to Asia empty.
So, that storage space will fill up quickly, and we're back where we started only now we have dangerously stacked high center-of-mass (because empty) containers (this is an active seismic zone, you know) that nobody wants to pay to get rid of until somebody dies and their insurance rates shoot up enough to make it necessary to dump the containers.
At which point, the shipping companies will magically make the shipping containers go away--probably illegally to somewhere you don't want them to go to.
