Seems like there's an adverse selection problem here. (And, relatedly, a signaling problem.) This is not an attractive option for companies at the head of the distribution or anyone aspiring to be there, and to the extent that you talk about it, VCs are going to read that as "You're a loser planning on losing."
From a practical perspective, one largely buys insurance to smooth out either cash shocks or future decreases in earning potential rather than for diversification. Having a startup fail is not going to be a cash shock. Your earning potential if your startup fails should go up, because you're worth six figures on the open market trivially, and you probably were not paying yourself that previously.
