We have had hydrogen pipelines for decades, and large scale storage in the form of underground salt caverns. These things basically work the same as what do for natural gas. The only real challenge was local storage, which pretty has ceased to be a problem with the rise of carbon fiber tanks. There are tens of thousands of FCEVs around the world, and rarely any issues with dealing with hydrogen storage.

The main limiting factor is infrastructure, or lack thereof. But the difference here is that you think it is technically impossible or at very least difficult. I believe it is simply a matter of building it, which is pretty straightforward.

BEVs also were impossible to buy for most people until around the mid-2010s. They went a century of near non-existence before then. FCEVs are simply going through a similar process. Sooner or later, they will be everywhere and BEVs will be abandoned afterwards.

You can buy whatever you want right now. It's not like anyone's stopping you. The point is that BEVs are not the answer. They are just a transitional idea and won't last.
