this enables the company to raise more capital by borrowing against its equity

You can always get asset backed loans, even as a company, why should we be welfare for businesses?

Also you would need an uncaptured market for anything you said to even have an effect, when 90% of trades are completed off market not effecting the price on the tape are we really doing anything but getting fleeced by market makers? You aren't signaling anything when your trade data is being bought and hidden from the market using PFOF techniques.

In light of the objective failures of our market it's extremely fair to say shareholders have no contribution to the delivery of goods and services. Could they in a perfect market sure, but I could have everything in utopia, to bad that doesn't exist.
