ESAs themselves, doing what they are meant to do, are absolutely wonderful, irreplaceable, and priceless for all they do to improve their owners' lives.
I agree with that. A year after getting my dog, now, I view getting him as a major turning point for me. I know nobody here knew me before I had my dog, but I was a mess. My quality of life is much better, my emotional issues (some realated to my disability) are much better, I'm more involved in my education and work. I finally have a real goal in life, and I think had it not been for him I would still be unhappy and struggling to get through every day. My two "petless" years (I had minimal contact with my parents' dogs and cat...I did however have fish and I worked at the vet clinic, but it's not the same. I got the fish because they were allowed in the dorms and I needed
something.) were the worst I have ever had to date. I'm actually thinking of writing about how my dog has changed my life for the local writing contest. I haven't entered in a couple years, but I used to enter and place (including one category win) regularly in high school, and I have the urge to write again

But that does not mean that just because a dog changes your life, you have the right to drag it everywhere. It's not good for the dog, it's not good for the handler, and it's not good for the public when an untrained or unsuitable dog gets dragged everywhere. The fact is that most doctors aren't aware of the laws involving service dogs, and many of them do think ESAs and service dogs are the same thing. When I went to get my letter saying Gavroche is an ESA, my psychologist actually said, "Let me write your service dog letter and you can pick it up next week." I corrected her that he is not a service dog and told her about the differences between ESAs and SDs. Just because a doctor tells you it's okay to take our dog everywhere doesn't make it right or legal to do so.
