I suppose that may be true--but there's an entire industry based on continuous lights--and it's very doable. Not to mention as time goes by light sensitivity will increase and improve as well.
Doable - yes, we do it all the times. For a price. A backpack for photography, a 35t-truck for moving picture.
The old sensitivity fallacy.
No, its not sensitivity that causes the costs(using Dedos for photography works ok for quite a few cases, same for L7, Seladors, KinoFlo/Creamsources), its the ambient light. No matter what you dial in on the camera, getting a decent contrast ratio takes the same effort, thus a Max18 for a nice annual income to replace a strobe set that costs about as much as a spare bulb for the Arri.
We're repeating the same mistake we did with video: believing it makes anything less expensive. Sure it the bills went down, because they cut all the people and stuff that make film look good, thus the stigma of video looking cheap. Rinse&repeat in HD.
