You're only unlikely to have no profits if you have no revenue. And you only get to break even 5 years in, which most startups will never reach.
In practice what is likely going to happen is that we'll see more and more startups deliberately avoid revenue in the early days. More and more free tiers followed by rug pulls when revenue actually becomes an asset rather than a liability.
There is no unplanned economy, only different outcomes from better or worse plans. And I'm having a hard time imagining a worse plan than one that intentionally disincentivizes businesses from adopting a sustainable business model early in their lifetime.
