The idea of capitalism is that capital accumulates in the hands of those who figure out how best to deploy and protect it. Investors, not Zhu, are the ones with the track record and experience.
Trusting them to be stewards of capital is a better bet than trusting an eccentric, unproven founder who decides to experiment with LSD for the very first time before a big pitch.
If Zhu had managed a successful exit, he would have established that track record, accumulated some capital of his own and bought himself the leeway to be as eccentric as he wishes in the future. See: Elon Musk.
