Just a bit of explanation, look at the worksheet in Publication 536:

https://www.irs.gov/pub/irs-pdf/p536.pdf

Line 1 does start as negative (a potential NOL), but then the next few lines 'add back' non-business deductions, including the Standard Deduction (Line 6).  When you work through the numbers, the Standard Deduction does not affect income to create a NOL.
