Worth it as a board to learn on? Would it instantly break with the stress of kite surfing?
Costco boards are fun boards and made for just having some of it. Since they've been made from foam they have great buoyancy and are great learning boards for surfing or SUP. Our beaches are full of them and even some unofficial foamie competitions are around.
I have a couple of them in my garage and use them to goof off in super light wind. Can you use them as a 'training board'? Sure thing; Best trainer for a strapless transition board and its water start. Because they are light they are easy to handle and you have to have your footing right to get up. BUT since they are foamies they are thicker and have a higher buoyancy, so edging and steering is a bit more awkward than a regular kite surfboard.
If you have kids or 'non-kiters' in your beach party then they are a must to bring: Less anxiety to use a board and less fear to break anything, because they are cheap ...
Well, a hundred bucks for fun and get-going or a grant for being left behind
