Because humans can't hear sounds higher than 22 kHz, so with a 44.1 kHz sampling rate you're guaranteed to capture everything humans can hear.

Besides, tape has wow and flutter and records invariably have scratches and dust, not to mention limits in dynamic range.

The analogous concept here is the product of sampling rate and bit-depth, the number of bits per sample i.e the precision of the recording
