It's a very exacting job calling for a very high degree of precision in:

1) Producing the correct lens shape reliably

2) Gluing elements together properly when required

3) Aligning them for the best result.

The work LensRentals do on servicing cannot be affordably included in/during the manufacture of ordinary lenses.  They are adjusting very expensive optics which are hired out for good money.
