This must be called pilot incapability, lack of try or BS. Problem is not to get kite in the air but to develop enough power to get going without losing ground. Looping kite constantly and dragging yourself slowly downwind is possible in lightest of winds but it doesn't make much sense.
Efficient foil kite can be pulled in the air in 0kn and flied in circles, then "wind " is the kiter himself. I was able to do this few years ago with my high AR kite even though wingtips weren't at all tuned properly. I got it somehow usable and I reached quite high speed with it but it was a bit too difficult to use and it was also pulling too much too soon. So I got tired of it and moved on...
For LEI's limit to get kite in the air is perhaps 2-4kn. In 6 to 8 knots I have had quite nice snow kite sessions with 17m LEI, but then surface must be of low friction and wind of good quality. Above 8kn almost all kites are usable in hard surface, no matter if it is LEI or small sized - assuming kiter knows how to fly a kite.
If surface is soft need for wind increases dramatically. If it is also light wind there is no other possibility than a big kite, bigger the better.
