For me, having a balanced system is only necessary for my home kegerator where the keg is expected to last a few weeks, the carbonation is consistent, and there is no serving issues with foaming. I keep a few 2.5 gal kegs on hand for "off site" consumption, where the keg will be gone in a few hours and I don;t care if a little co2 comes out of suspension. So, for that short term use, that tap without beer line is perfect. But I agree, it's not a perfect item for all situations.
