Agree completely, in any applications where strands of silk is needed the worm-spun threads are the most cost-effective solution and presents a far superior product. All the applications where threads are needed, the Moon Parka for instance are laughably unusable. And the cost of protein purification must be astronomical, it is hard to imagine even a cost-effective bulletproof west not just a t-shirt. That's why i bought shares in KBLB.

However in the direction where Spiber is going, for instance the silk coating of medical devices, the vat-grown silk seems to be superior. Protein purification costs a lot, but medical devices are already as expensive as they get and not a lot of silk is needed. However worm-spun silk contains a horde of other molecules (other proteins, chitin, etc.) which makes it totally unsuitable for this kind of raw usage. And if you need to purify and reconstitute the silk, then it is entirely possible that the yeast produced silk is cheaper.

I am just saying that as the anti-GMO useful idiots protected Monsanto's business for decades by purging every other company from the market, it can be expected that it will be much harder to enter the worm-spun spider silk market than the fermented silk market. In China, the most likely candidate where unlicensed silk operations could take place (and capture KBLB's profit) the complete GMO ban will hinder any kind of operations like this. And the situation will likely not change in ~5 years.
