Yes, but we, unlike those countless others, have the ability to use technology and tools to our advantage.
And our disadvantage. Using this technology, we will continue to extend our lifespans and eventually breed ourselves to death, if an asteroid doesn't take us out in the meantime. You heard it here first. Film at 11.

How does physics prohibit human spaceflight?
It doesn't. It does, however, prohibit colonization of anywhere not on this planet (let's agree to define a colony as a self-sustaining entity, that can survive without support from the outside).

Compared to trillion spent on the "war on terror", the $20 billion or so that NASA gets every year is very much worth it!
Amen to that, brother. No argument there.

It is up to us, the people of the present, to make access to LEO cheap and reliable, and to settle and colonize other worlds in case some disaster strikes home. Haven't you ever heard of Carl Sagan's "two planet" rationale?
Carl Sagan? You mean the guy that wrote a novel about aliens sending us plans to build a warp engine/time machine? That Carl Sagan? What I
haven't heard of is a world that we could possibly dream of colonizing. If you are going to assemble the world's greatest engineers to solve a problem, I'd start there. Engineers don't do well with ambiguity. Spoiler alert: there aren't any.

[Engineering] is perhaps the "easiest" thing to deal with when it comes to manned spaceflight.
It's always easy for people not doing the work. Engineers, Apollo is a good example, only make it
look easy. That's why I love 'em.

The problem is pessimists and misanthropes who constantly oppose anything that can expand human presence in space. Without them things would go much smoother.
Wait a minute now. That's
Mr. Misanthrope to you, Yuri. Why, I'll have you know that skepticism is necessary to the scientific method. It can separate mythology from truth. Galileo is my recent example. Don't make me turn on my Rene Descartes signature again. Oh, HSF fans will have much much bigger problems to overcome than a misanthrope who loves scientists, pilots, physicists, engineers, and continent of literate readers. Come to think of it, I'm really not a very competent misanthrope.

We've been doing it for 12 years non stop now.
Er. No. The space station is not a sustainable colony (see my definition above). And I wouldn't even call it very efficient. As far as I can recall, it has failed to make a single one of its original design goals. Could be wrong on that. I'll have to check.

If you despise manned spaceflight so much then why are you in a forum that discusses not the rationale for human spaceflight but the technologies and programs involved with it?
Well, they seem a little interrelated to me, but in any case, I am far, far, from despising manned spaceflight. In fact, I would still give the proverbial left body part to be able to fly on the Shuttle or
anything into orbit. Somehow, however, NASA prefers people like Lisa Nowak to someone like me who has actual passion for flight, engineering, design, and discovery. So I remain earthbound with all my glands intact.
What I despise is senseless waste of resources, as should we all.
