Not everyone enjoys standing for extended periods of time while playing a game. It certainly depends on the game, for me.
In regards to the Wireless Sensor bar, I can relate to the desire for the convenience of one. One of my friends or I often bring a Wii to an auditorium here on campus, and with such a large projected screen, it's difficult to find a place where the sensor bar will reach and will feel natural to point at.
If you're interested in a Wireless Sensor Bar, IGN has a review of one
here.
This guy didn't ask for your home decor suggestions, so it'd be great if you stop telling him how he's supposed to play.
