I agree with you the trade war is likely to have far more of an impact (at least an order of magnitude) than any of this, however as companies like Uber go public it no longer is only affecting private investors. And Softbank definitely propped up Uber for the IPO like they tried to do with WeWork, but I guess that was a one trick pony.

Also let's not forget how many pension funds are tied up in VC portfolios, so while it may not have an immediate crashing impact on everybody it can ruin people's retirements.
