Could you provide some data to show that companies which, at IPO, have any cumulative loss or a very large cumulative loss (as a percentage of valuation or offering size), perform worse as investments or as going concerns?
From your other comments, it seems like the foundation of your proposed change is that going public with significant losses is an attempt to get less-sophisticated investors to compensate more-sophisticated investors.
While there are many arguments against your proposed change, the first step seems to be establishing that the problem you’re trying to solve actually exists. I’m not convinced that it does (but don’t have data either way - that’s just anecdotal), and in fact many - maybe most - institutional investors in private companies continue to hold post-IPO shares long after the lockup (and gradually sell over 1-3 years simply to diversify).
As you investigate this, it might be worth reading about the “CAC payback period” and how it can lead to significant upfront losses: https://baremetrics.com/academy/cac-payback-period, https://kellblog.com/2016/03/17/cac-payback-period-the-most-...
