I actually have wondered if stock-based compensation will be more common on a bitcoin standard.
The issue I'm imagining is that if you have an appreciating currency, rather than employees getting regular raises to keep up with cost of living they would need to get regular pay cuts to adjust for declining nominal revenues.
Employees don't like pay cuts, so an alternative would be to have smaller fixed salaries with larger amounts of profit sharing.
I think you're right though about employees preferring to just get monetary compensation. Profit sharing is theoretically more efficient, because of the incentives, so if you're doing profit sharing it has to amount to more total compensation.
