I agree that working with a bunch of musicians is always going to be an interactive experience that can lead to interesting results that may not be found when working alone. The whole "band" idea has always been dear to my heart...and I don't much like how these days so many band musicians are nothing more than band whores, and it's not about the music or about creativity...it's about getting a gig and a couple of $$.
I much more prefer having a band that sticks together, gels and turns into a more singular unit, greater than the sum of its parts...and where the idea of a "band" is one of solidarity.
Maybe that sounds corny...but that's the only kind of band I would want to be involved with.
That said...bands are not easy to form, not easy to gel and keep together, and often end up being more of a waste of time and a PITA, than serving as an inspirational creative unit that makes great music together.
Making music solo is not just "programming"...even for the guys who are mostly working ITB.
Before I got into digital, I use to kinda think that way...but having straddled both OTB/ITB ways of working, and using both analog/digital formats for the last 20 years now, I realize more and more that...
...if you focus too much on the gear and/or the processes that you use, you will always have some negative perspectives about people doing it differently than you.
Every aspect of a recording project done solo is still all about "making music".
That said...if you feel you need to use an upright bass instead of an electric one...or a real drum set instead of sample, or a guitar amp instead of a sim....than do that.
Considering that most of the guys here are using computers and recording solo, and/or having to assemble and mix tracks from solo takes in order to make their music...I find it odd that there are all these hard lines being drawn about what music really is and what its purpose really is.
I dunno...for me, the main purpose is to satisfy my own creative drive and recording interests, and to please myself when listening to it.
Anything more than that...is gravy.
YMMV......
