An injury that leads to tons of blood loss is very traumatic for the body. A needle that extracts some blood barely registers. These aren't equivalent things.

People needing blood often need multiple transfusions as they are actively loosing blood. The transfused blood buys surgeons time to find and stop the bleed(s). A person donating blood is losing a controlled amount of blood that is safe to lose.

If you lose too much blood organs and tissue start to die due to lack of oxygen. We can't reverse this damage and depending on what died our body is also limited or incapable of repairing the damage too.

Transfusions try to maintain enough blood in the body so the heart and lungs or a bypass machine can keep your body saturated with oxygen. A person donating has no risk of this.

Your body can't just magic out liters of blood. Where would it come from?

Water is key for life as we know it so having a bunch of it is good for life. There is basically zero chance Mars had anything past single cell life. It took life on Earth billions of years to go from single cell to multicellular. Mars lost its atmosphere and oceans early on. There wasn’t enough time for life to evolve like it has on Earth.

The US banned China over concerns of intellectual property theft. In the last decade China has done nothing to show that they respect international patent laws to the same degree as the West. They've recently been accused of stealing trade secrets from TSMC to get their own chip fabs up to par.

The US doesn't see that as a mistake.

This isn't true. They aren't trying to cause a panic. Some of their rockets uses a sustainer centre core that makes it into a very low orbit. They haven't invested in the tech to relight the engines or add deorbit motors to deorbit it in a controlled fashion.
