If the only usage case for hydrogen fuel is driving hybrid passenger vehicles, then you would have a point.
Is that what you mean? Be specific. Or are you imagining a broader use for hydrogen fuel cell vehicles? You have already described hydrogen haulage trucks to deliver the fuel. In your mind, does this hydrogen fuel infrastructure serve any other transport type?
Anything else? Or just those two?
If you are trucking energy to the user, and each truck contains (say) 1 / 50th of the energy. How many trucks of gas will you require for a drop-in replacement for transport fuel? There are some efficiency gains, because fuel cells are more efficent at converting fuel to motion, but this is absolutely offset by the inefficiencies to store the energy in the form of hydrogen. A diesel engine is something like 35% efficent. Stem reforming hydrogen production is a lot less efficent than that.
I'll make this as simple as I can.
In fact, a road tanker which transports high pressure hydrogen as compressed gas might typically carry 300–400 kg of H2 and be able to refuel up to about 100 cars.
Whereas a typical diesel tanker typically carries between 20,800 to 43,900 L in the USA.
Large trucks typically have capacities ranging from 5,500 to 11,600 US gallons (20,800 to 43,900 L; 4,580 to 9,660 imp gal). In Australia, road trains up to four trailers in length (known as Quad tankers) carry loads in excess of 120,000 litres (26,000 imp gal; 32,000 US gal)
I'm done here. Have a great day.
