The most relevant response to Lakshmi’s situation is: She can’t rely on the rest of the editorial staff.
When she was working full-time at a magazine, she likely had access to an editorial team that would support her with copyediting and proofreading. As a freelancer, she will be responsible for ensuring that her work is polished and error-free, as she won't have that same level of support available. Therefore, honing her copyediting and proofreading skills is crucial in order to maintain a professional standard in her freelance work.
