All true today, but it does have a bright path forward as a structural and electrical and thermal material. The length and size of the bits today is small, but it's already gone from being batches you grow to being a continuous mfg process, and that process has seen regular improvements in the size of continuous single layer defect free sheet.
The feedstock materials to make graphene are so cheap (methane and/or CO2 and electricity), it may be in the next decade or two even disposable drink containers will be made from graphene, possibly grown into a can shape with no adhesive required in our lifetimes.
Soon enough, a cheapy wallmart bike will be all carbon and under 10lbs. Graphene and CNT based bikes will be under 5lbs stock.

On top of that, there are surely health risks of exposure to graphene that will come to light with more widespread use of the material. I don't want to live anywhere near a shipyard that uses the stuff. This is a much more wicked material than asbestos from a cellular standpoint, and the more effectively they can make relatively large particles of it, the worse it will be.
Each carcinogen vapor exposure includes a dice roll for cancer.
Each mutagen vapor exposure includes a dice roll for reproductive genetic defects in your children.
Each engine start sprays them into a shared atmosphere which includes beings not offered an opportunity to consent accepting these cancer experiences and defective genetics life experiences.
Every post is a free gift to the collective of minds composing the living bleeding edge of LEV development on our spaceship.
