Maybe in YOUR world, but in the real world, people make choices on how they spend their money. There are lots of cheaper ways to be entertained than a motorcycle race. Prices do matter.
They matter to me. I took JUST tickets and parking for COTA, because the VIP packages were outrageous to me. They started at $850. F' me. Would you pay that? I always do some VIP at Laguna - for one half the price.
I don't know Laguna's contract arrangements, but the reason that the 125s and 250s didn't originally come back to Laguna was because it was against California law to race the two-strokes. Moto2 started in '10, and in '12 Moto3 started. They may have to come together, and Laguna may have already had '13 contracted out. I don't know. There are other issues, but don't assume that SCRAMP left out those classes because they wanted to do so.
That is not likely to happen. The track is
barely safe enough for AFM. And even a stock liter bike is starting to get stupid out there. I like the track, but a WSBK guy would be shifting like three, maybe four, times an entire lap.
