Bizdev is a concern when you have the Cardano with Charles Hoshkinson who is arguably the best in the business at that. It is true that partnerships and bizdev make the difference between a market cap in the hundreds of millions vs market cap in the billions or tens of billions. Tauchain has the potential for a market cap in the hundreds of millions or tens of billions but as I've expressed to Ohad himself this is all going to depend on strategic partnerships.
I agree with you that Ohad himself is not the best person for that job. I do not know exactly who should do that but Tauchain in my opinion requires partnerships in academia, at the very minimum, just to attract enough brain power to develop it.
