I am thinking for those who wants to hold bitcoin, this is the perfect opportunity to acquire bitcoin without having to buy it on your own. Lessens the steps to be taken but I see your point because after all, you would not be using all your salary to buy bitcoin so at least half has got to be converted to fiat. But if there could be a time when even grocery stores accept bitcoin then that problem will be solved.
But the question is when will that become a reality, or will it never happen? Honestly, I highly doubt it.
And right now, fiat money is still the main payment unit, so it would be inconvenient if our salaries were paid in bitcoin, even for those who want to hold bitcoin for the long term.
Because if I remember correctly, you once gave this spending formula in this order: Necessary expenses→Emergency fund→Savings→Investments. But when you accept bitcoin payments, you are doing the opposite of your own ideals.
