Because mmmmm, tape compression.  You can fake it in digital, but it's not
the same.

Bob Katz begs to differ:
"I believe that a finely-tuned 30 IPS 1/2" tape recorder is more accurate,
better resolved, has better space, depth, purity of tone and transparency 
than many digital systems available today. Empirical observations have 
shown that you need a nominal "24-bit" A/D to capture the low-level 
resolution of 1/2" 30 IPS (if truth be told, the best converters only 
approach about 19-20 bit resolution in practice). It can also be argued 
that 1/2" tape has a greater bandwidth than 44.1 KHz or 48 KHz digital 
audio, requiring even higher sample rates to properly convert to digital.
Listening tests corroborate this. 30 IPS analog tape has useable frequency
response to beyond 30 KHz and a gentle (gradual) filter rolls off the 
frequency response. This translates to more open, transparent sound 
than any 44.1 kHz/16 bit digital recording I've heard. 1/2" 30 IPS 
analog tape has lots of information, like high resolution 35 mm film. 
16-bit 44.1 KHz digital is like low-resolution video."

Assuming the mastering guy's gear is well-maintained, his price may well
be worth what he charges.
