Permission to set Disqualified/Lost Leads to a different stage
SOLVE
You could work around this with a workflow. Allowing you sales and customer service staff to update the Lead and re-open it. In context of the need from a service standpoint, sometimes our customer service staff will hear back from the contact after they have disqualified the Lead (simply timing from the potential client), so they set the attribute to jog the workflow to re-open the Lead.

Creating a new lead is the better option, in my opinion. This is the whole point of the lead object if you ask me. It allows the sales reps. BDRs to close a lead that is considered not qualified at a certain time but might be qualified in the future to manage them as a separate lead. I would automate this.
