We don't need the physical storage capacity immediately just lease the tankers now to get the spot oil prices or commit to set delivery dates to give enough time to buy or lease the land and build the tank farm. That is, if we can even get a tanker.
Being coastal, when/if things get back to normal, and we've used up the cheap oil, we can turn the tanks into fish farms.
If it's Greta's worst nightmare, it might be a good idea.
