I suppose 'real' or 'true' bushcraft depends on your definition of bushcraft. If it just means being confident and comfortable in the natural environment then that could encompass a whole host of things from farming to living like a tramp!
The Oxford dictionary definition goes something along the lines of 'skills pertaining to life in the bush.' I think 'skills' could be opened up to 'craft' and 'knowledge applied practically'.
If you were to live life in the bush then you'd probably bring suitable clothing and the appropriate tools. You probably wouldn't, however, be able to bring all the food and consumables necessary for that life in the bush. I would include tinder as one of those consumables. You would have to learn which tinder was available in the bush and develop the skills to make use of it. In other words you would have to use bushcraft.
I used to use dryer fluff when I was first getting into this hobby. It's a reliable way of getting a flame from a spark. But I wouldn't use it anymore, I'd use a match if I had no natural tinder.
Each to their own, light fires how you want to light fires but I believe people are kidding themselves if they think using dryer fluff as tinder is bushcraft.
I'm having difficulty imagining the Ray Mears programme where he goes into the utility room of his house and extols the wonderful properties of dryer fluff as firelighting material
