That said, I actually have sympathy for the stigmatizers. From their perspective a perfectly healthy person with no overt negative stimuli is profoundly unhappy for no reason. That's got to be frustrating because it's completely and totally opaque, untouchable, alien, and unaddressable. The condition stymies the compassionate person, making a mockery of their good intentions. That is frustrating, even angering, and is probably the cause of the ambient hostility that lingers around depression. Depressives behavior appears stubbornly self-destructive, which essentially and irreducibly thwarts the will of those that care for them.
People going to their GP with a 'I feel depressed' that get told 'well, here's a prescription for some pills, let me know if you feel better with them if not I can give you something else to try' would be the same as if somebody reports a thorny concurrency bug with your embedded multithreaded application and your first response is 'well, let's try to overclock/underclock the CPU to see if it improves things, if not maybe we can try to change the RAM next time'.
It is a lot cheaper for medical services as a whole to have GPs easily prescribe antidepressants and psychoactive drugs in general rather than have psychologists available immediately for anybody who might need them, but it does not make it right.
Others might not share my misgivings but I would only be willing being prescribed a psychoactive drug by a specialist (psychologist/psychiatrist) after a thorough evaluation and non-pharmacological therapy first, and even then very conservatively and after an explanation more objective than "you have a chemical imbalance in your brain" (which chemicals? what imbalance? what should be the normal values?).
There should be much easier and cheaper access to non-pharmacological treatment for mental issues, but maybe to have that one would need it to be destigmatized, which of course is a very slow process and might or might not be possible due to the identification we have with our minds: if our knee hurts we think "my knee hurts, it needs fixing" if our mind hurts we think "I feel bad, I am a worthless person" which is a lot harder to deal with unfortunately.

Everything actually is pointless, since all matter and energy will dissipate from entropy on a long enough time span. Also everyone you know will be dead in 100 years, most likely.
Also most of these people would go see their doctor if there was a million dollars in gold waiting there for them. It's not that 'everything is pointless' is the reason preventing them, but rather that there isn't enough significance in seeing the doctor.
I'll caution you against this thinking, in general. If you have a depression so severe it keeps you from seeking help, you're probably well aware that it's a matter of life and death. Even if you're not acutely suicidal, you live day to day just "running out the clock", hoping it doesn't get any worse before you die. The prospect of wealth or fame in your future is not only not enticing; it may well make you feel worse, as self-awareness of your inability to care reinforces your depression.
The idea that people who are not motivated by death will be motivated by money is, while not categorically false, surely fraught.
Merely anecdotal evidence of course, but I don't think you're on the right path here
If you break your knee, you will (99.9% chance) go and see a doctor. If the first doctor doesn't fix it, you'll see another. Your knee is broken, unusable, painful and you have a drive to fix it.
A more serious injury will generally result in a friend/family member/passer by getting you to a doctor.
If you suddenly enter a depression... even getting to the stage of seeing a doctor can fail, because suddenly everything is 'pointless' (bad wording. sorry.). And if you see them and they give bad advice, you maybe can't be bothered to see the next one. Or you miss the appointment because getting out of bed was too hard. Etc.
It's more severe than most physical injuries because it affects your ability to seek help.
