I don’t think the blog post is written by an author thar is currently poor and is therefore wasting their precious time writing blog posts instead of figuring out their life.
I think the point it’s trying to convey is that people too often blame the poor without stepping in their shoes.
If you think that conversation isn’t “very productive” I’m not sure what planet you’re living on. Certainly not the same planet where the world’s richest country is trying to cut food assistance, add work requirements to social safety net programs, refuse to make even the most basic healthcare services universal, cut the basic healthcare services that it does provide the poorest, and generally has a cultural zeitgeist actively hostile to people in poverty.
You say that the poor person whose car broke down should just magically stop worrying and do something productive like find a solution, but don’t you think that having to do that constantly sounds a bit exhausting?
As someone who is not poor you have no need to train your brain to ignore survival alarms like that. If your car breaks down you have ample options, just throw your uber ride on a credit card, take your car to the fancy dealership that will give you a courtesy car, own a second or third car, or own a nice new car that will never strand you in the first place.
Your belly never feels hunger for too long, your body never feels excessive cold or heat, you don’t feel the pain of untreated preventable health conditions, you don’t feel your body aching from working multiple physical jobs, you don’t feel the adrenaline rush of being mugged or hearing bullets fly in your neighborhood, the police don’t work with a heavy hand because of where you live and they don’t harass you for how you look, you don’t breathe the pollution and don’t hear the noise that disproportionately impacts lower income neighborhoods, [1] you don’t have the government coming to move you and take your house because it’s cheap and convenient to do so.

Those are actual physical survival feelings that you’re just telling the poor to stop worrying about.

[2] Here’s a random example: the LA Dodgers stadium was built on the site of a working class neighborhood where the residents were kicked out in a fiasco that can only be described as an abuse of eminent domain: https://en.wikipedia.org/wiki/Battle_of_Chavez_Ravine
