Lifestyle Issue., A treatise on the street. Options

[WiredWeasel]

Alright, I'm wondering how on or off the grid should a shadowrunner be? Just how unplugged can you be and still function as a decent runner?
I ask because one of the characters in my group wants basically no gear, and is adamant on a street lifestyle. He's the magic oomph in the group and is the Street Shaman.
Okay, on a character background and development level I have no problem with this, my problem is how much will this hinder him, or hinder the game? Am I overthinking this? He may pick up a few magical goods but wants nothing else. He really hates the idea of even a beat-up taped together commlink and would rather have none. He's also taken the computer illiterate neg. quality. He's all magic and spirits, so it could work, but I'm concerned.
So yeah, how hard is it to be a good mage runner and basically be homeless and penniless? Also feel free to openly discuss any weird lifestyle issues your players might have brought up. It's always good to have perspective.
