There are a lot of logistical reasons why this is a really bad idea, but here are a few quick ones off the top of my head:
1.) I assume people would want to record themselves doing something a bit more interesting than just walking in a wide open area at the same pace where 100' of cable can't get snagged on anything.
2.) Any sort of quick changes in direction are going to tug on the wire, at worst risking causing the drone to crash, at best causing the video to take you out of frame.
3.) If there's any sort of speed involved, the drag of that wire in the wind will eat up power.
4.) The weight of 100' of cable will add up quickly, especially if you want it to be robust enough to handle being snagged/tugged. You certainly don't want a break in the cable, because a sudden loss of power will be catastrophic.
