Consider what sort of DSLR bundle a novice needs to get the flexibility of a Bridge:
Camera Body
"Marco" lens/Extension tubes
"Kit" lens
"Zoom" lens
"Wide Angle" lens
Now carry all of those lenses, constantly changing between them on something like a hike (where you'll probably want all of the above ability) and you'll see how versatile the Bridge is for beginners.
Yes, for more advanced elements like DoF or tough scenarios like low light shooting a DSLR wins hands down thanks to an extended range of lenses (and larger sensors, and more AF points, etc.), but that's the next level IMHO, beginners should focus more (see what I did there) on taking pictures before investigating advanced techniques.
I was on a gondola in Venice last year in the early evening, armed with my Canon 60D, my GoPro Hero 4 Silver and my Galaxy Note 5. Unfortunately the only DSLR lens I had with me at the time was a Sigma 10 - 20mm wide angle with minimum aperture of F4.5, which really struggled to capture the scene (lower shutter speed didn't work due to the movement of the gondola). So the R15,000 worth of camera and lens I had with me took a back seat to the mobile phone (thanks to it's F1.9 lens).
Also, this topic made me think of a What The Duck comic:
