Bitcoin is not a threat to centralized currencies, there is room in the financial world for both. A government controlled currency has some clear advantages, relative stability being one of them. I wouldn't accept paychecks in bitcoin for the same reason I wouldn't accept paychecks in gold bullion, although both have a demonstrable value, government issued currency provides a stable way for the average person to store wealth at scale. Although everyone sneers at the federal reserve, their financial engineering plays a real role in perpetuating western affluence (though it clearly has serious problems; a topic for another day).

The significance of bitcoin is that it's an unrestricted option for anyone at any time. Just because you won't accept your paychecks in bitcoin doesn't mean you won't want to use them from time to time, if only for the freedom to bypass the astonishingly ubiquitous banking institution. I'm not even talking about anything illegal (though illegal doesn't always mean wrong), I'm talking about the minefield of wealth draining fees and bullshit (frozen accounts, chargebacks, spending limits, really slow transfer times) that bitcoin lets you avoid when you want to.
