Yes, that's essentially what I'm saying, but I wonder if there aren't some better alternatives to incentivize early employees when cash is scarce. Maybe (just off the top of my head) something like a contract to pay the employee a set dollar amount (with interest) at an undetermined point in the future, and it must be paid before any profits can be distributed to owners (there could be other triggers as well). This would be in addition to the employee's salary, which is likely to be at below-market levels when the company is still young.
It could come with additional features similar to a vesting schedule, but essentially it would (1) give the employee a known dollar amount of compensation contingent on the company's future success, (2) allow the company to remain private (if desired) while still delivering the "carrot", (3) avoid the need for an option pool, and (4) avoid the issues I described in my earlier comment. After some or all of that amount is paid to an employee, the difficulty in keeping the employee around is no different, but at that point (where profitability allows for the payout), a company is more likely be in a position to offer/renegotiate competitive salaries in the first place.
Then again, a lot of founders/owners probably don't want something so concrete because of course they benefit from being able to attract talented people at a discount by offering a tiny bit of equity and the dream of becoming a millionaire when the company IPOs or gets acquired. Heck, I've been there - on both sides of the conversation. But the truth is, a lot of people are realizing that equity isn't usually worth what a founder thinks it is, so that's becoming a less effective bargaining chip as time goes on.
