Someone has to get paid to do that, so now the premise of equity crowdfunding has been reduced to: in the best case, you can crowdfund another venture capital firm, and pay a tax out of your returns that wealthy investors don't have to pay.

And, again: most VCs fail! A lot of money is invested in VCs not in the expectation of those investments being lucrative, but instead in the hopes that VC returns are uncorrelated with the public markets. But no retail investor does that.
