It might greatly depend on what style of music you make, but for my workflow there isn't really a good analogy between a band doing multiple takes and me doing bouncing down in a DAW. The main difference for me lies in the automation -- for example if I have 5-6 instruments playing at once, of course the melodies in my genre come first, but closely behind that in priority is automation. Once I bounce it to a waveform there is not much I can do with the synth instruments in terms of automation. I can of course manipulate volume, the cutoff etc for the entire track, and add FX but by that time each instrument is closely married to each other, and I can't for example add a delay to only one instrument out of those six, which might be actually two mixer tracks combined into one (representing 12 instruments in this example). So instead of being able to do some automation with delay or chorus or a synth control like phase or morphing against one of those instruments just to change it up a bit, I can only do it against 12 instruments at a time and I must use mixer effects rather than synth controls.
Does that mean the music will sound worse? Definately not, in my case actually the less I screw around with the better off I am

How good the music is ultimately has very little to do with what's available as much as what you do with it and what you're willing to accept as the final take. But, when I cannot modifiy the individual components of the track it feels so limiting to the creative process... it's purely a mental thing, I know... but I just wanted to make clear it wasn't so much an issue of laziness on my part, it doesn't take that much effort. Its just if I want to reap the benefit, I'm going to have to come up with a final take on a track early in the creation process, or be willing to keep revisiting it later.
