Can I ask you something? Why does Xanax have a street value? Why does Valium have a street value?
Mostly, because it is used by drug addicts to moderate the effects of the drugs, or help them cope with withdrawals, not usually to supply the unmet needs of anxiety sufferers, though it could be argued that many addicts became addicts because the drugs relieved an unrecognized disorder. There would be few of them posting here at AZ, but I find it interesting that you appear to be lumping the BZD street drug issues together with BZD in the anxiety community.
Most of those taking these meds for anxiety do not abuse their benzodiazepines. Indeed, the evidence is that most reduce their doses over time. To quote possibly the most zealous anti benzodiazepine campaigner of them all, "Given the number of people who are prescribed benzodiazepines, relatively few patients increase their dosage or engage in drug-seeking behavior.....Abuse is frequently associated with adolescents and young adults who take benzodiazepines to obtain a high. This intoxicated state results in reduced inhibition and impaired judgment. Concurrent use of alcohol or other depressants with benzodiazepines can be life-threatening. Abuse of benzodiazepines is particularly high among heroin and cocaine abusers. Approximately 50 percent of people entering treatment for narcotic or cocaine addiction also report abusing benzodiazepines."

I doubt that many genuine anxiety sufferers sell their benzodiazepines, but that street BZDs come mostly from illicit drug users gaming doctors, both to get BZDs for their own use and to sell to buy illicit drugs.
And anything that can cause euphoria will be abused, misused, and people can become addicted to it.
Yes. But in this case they can also help people when nothing else will. Most of those prescribed antidepressants don't take them long enough to get any benefit because they can't tolerate the side-effects. Of those that do, about a third derive no benefit from them, another third do not get full relief. How do you propose they be helped? Therapy? Sure, it can be highly effective. but for many Americans it is about as accessible as the Moon. Plus, just as with antidepressants, therapy doesn't work for everyone, and there seems to be a large overlap with those not helped by antidepressants.
So how do the medical zealots then help these people? What answer do they have? Usually, none, IME. They often just leave their patients to to fend for themselves, resulting in many leading miserable lives. The zealots don't care that in fixing one problem they make life miserable for many others as has happened in Britain where benzodiazepines are almost impossible to obtained from NHS doctors. This has lead to deaths among those who unable to get adequate relief for their anxiety give up on living, something which will only get worse as the push there against antidepressants gains more and more traction and the number of available therapists proves inadequate.
And while I have your attention, maybe it is time you leaned about the difference between addiction and dependence, which is knowledge you seem to be unable to process. Perhaps this will help, it's mainly about opiates, but is just as applicable to benzodiazepines: Definitions Related to the Use of Opioids for the Treatment of Pain: Consensus Statement of the American Academy of Pain Medicine, the American Pain Society, and the American Society of Addiction Medicine (PDF
