What are you using jackstands for in changing wheels? I do this twice a year and have never even entertained using jackstands for this and can't see any benefit to using them. Also never had any need for a breaker bar. I just loosen all the lug nuts about 2 turns and drive the car back and forth about 3 feet a few times to make sure they're all free of the hubs. Never had a problem getting any wheels off. I do use anti-seize on the hubs, though.
The benefit of using jack stands is that they won't drop your car. It's rare, but hydraulic jacks can, and do, fail. Or someone accidentally bumps and handle and releases pressure... or the jack isn't lined up quite right and it slips... you forgot to set the parking brake or leave the car in gear... shit happens, albeit rarely. I'll usually only use 1 or 2 at a time, FWIW. Again, one of those things where the cost ($20 on amazon + 2 minutes to grab the stands) is trivial compared to the consequences of something going bad: dropping the car and damaging brake rotors and suspension bits, or getting an arm/leg caught under the car.
I dislike driving a car any distance (even feet) without tight lug nuts. To break wheels loose I just give it a good kick with my heel on the tire and they pop right off. In
very rare cases I'll put a 2x4 across the wheel and hit it with a 3-4lb hammer. I also use anti-seize on everything (studs and hubs) so my own vehicle's wheels just drop off, never ever had them seize on when I use anti-seize (go figure that one).
I use a breaker bar not because it's required, but because it makes life so freaking easy and they are relatively cheap. Sure, I can loosen a lug nut with a 1/2 driver, but with a breaker bar I simply don't need to try as hard to break things loose or tighten them up, it makes life really easy. Heck, my petite fiance can break lugs loose and set their torque with 2-3ft breakers and torque wrenches without much effort.
