We know how to make people live longer – provide them with good healthcare from cradle on, reduce pollution, help them out of poverty etc.

Biggest problem with people living longer is the costs of supporting them increase dramatically, and who's going to pay these costs?

Increasing longevity places a burden on our children, and their children

You're confusing (deliberately?) a few different things.

(1) better healthcare, reducing poverty etc. lift the floor of longevity but not the ceiling

(2) "cost of old age" is exactly what longevity research attempts to reduce - noone is interested in living longer as a vegetable; instead, the goal is to increase healthspan - living healthier for longer

Better healthcare, reducing poverty etc., lift the ceiling.

In many parts of the worth we are living longer due to these things (or were before Covid)

Longevity research may also be interested in lifting this further but are all these people who now live cor even longer going to want to carry on working?

If not what are they going to live on, how are their pensions going to be paid for, how are we going to mitigate the extra demand placed on earth etc.?

I'm going to die one day and I'm fine with that

That's the logic of mass homicide. How many children would you kill now, today, to spare the generation after the burden of taking care of them? Why haven't you killed yourself to spare (y)our children the pollution your existance causes?

Humans are a burden to humans, but we're also humans' best shot at prosperity. Let's not be so quick to deny the upside of living longer, healthier.

(That said I agree with you that up to age 80 or so the recipe for general healthspan is very simple and up to personal responsibility)
