The great thing about soccer is that even having an actual soccer ball is not a necessity. Empty cans, ragged tennis balls, anything will do. This used to be perfectly fine in the first world country I grew up in, so although this is a great product, it doubt it will make as much of a difference as the author suggest. Kids will play soccer and enjoy it no matter what.
The point is not so much to get kids playing soccer: they do that on their own. The point is safety: if the ball holds up, they won't resort to making their own from unsafe materials.
