Unless you plan on making your own vocal or acoustic instrument samples, most of that equipment isn't necessary.
Samples? Some of us record audio tracks, we don't use MIDI for everything. For example, if you want to record your band at home, you might have six microphones just to get started (vocals, guitar, bass, snare, kick, and drum overhead). Outboard limiters and microphone preamps are not out of the question. On the other hand, if you do everything with software samplers and synthesizers, then you just need a computer, Lo…
Now you'll argue that a bottom of the barrel high end amateur grade mic might be only $50. But you'll still need cables, probably a preamp, some kind of (expensive) interface box to input 6 audio channels in phase (can't just plug in 3 stereo usb sound adapters... well, usually...). A decent stand or boom is probably $75 for a hunk of metal. Suddenly paying $50 for a cheap mic is false economy if the support infrastructure is setting you back $300... may as well buy a decent $200 class mic... to go with your $200 software.
Unless you're solely a vocal group you'll probably need to mic and input instruments.
My sister used to play the viola (more or less a big violin). A pro grade mic costs $400. Not a viola with a mic installed. Not a package deal of mic and cable and preamp and all that. No, just the custom designed weirdly mounted mic. Before permanent professional installation of course. This is probably an extreme, obviously its hard to mic a stringed instrument without screwing up the resonance sounds while the musicians face is inches away from the mic. I bet you could mic a brass instrument for a quarter the cost.
