Depression wholly or in part caused by external factors is still treatable depression
I was thinking more about reasons why people don’t go to therapy. Cost (or hoop-jumping to avoid cost), transportation, paperwork, waiting lists, scheduling. Also other blocking issues, like physical health problems, housing situation, personality disorders.
For the US there will likely be a wave of cuts to benefits in the next year, so that does not inspire confidence especially for medications that cannot be quit/switched on-a-dime or medical operations that require follow-ups.
Also when it comes to hobbies, a large part of it really does boil down to money (materials, tools/equipment, space, fees for events). Though other problems (transportation/sparsely-populated area) can also mean a lack of help when running into issues.
