...with our technology, we should be able to visually confirm the landing sites from the hardware that was supposedly "left" behind,,,i.e. the landing gear of the LEM etc....
Not as easy as it appears. Without getting into too much detail, it is far easier to see a white spot against a dark background, than the other way around. You can easily prove that too yourself with your eyes, and a camera. Remember to use full sunlight for the bright background. The Hubble telescope would not be able to resolve a LEM on the moon, even without the contrast issue. If the LEM was in deep shadow and on fire, then it could see it. It wouldn't look like much though.
What speed do you need to get to low Earth orbit starting from the surface of the Earth (ignoring air resistance)? Answer: 8133 m/s (18,136 mph)
What speed to you need to go up into space (but not orbit)? Answer: 2,715 m/s = 6054 mph.
What is the escape velocity for Earth? Answer: 11,176 m/s (24,923 mph).
How much do you need per kilogram of mass to get into LEO (Low Earth Orbit)? Answer: 3.31 x 10⁷ Joules.
How fast are you moving due to the rotation of the Earth (at the equator)? Answer: 465.1 m/s (1037 mph)
What is the difference in speeds to get to LEO at the equator vs. the North pole? Answer: 7667.6 m/s (17,099 mph) at the equator and 8133 m/s (18,136 mph) at the North Pole.
What is the difference is speeds to get to LEO at sea level vs. a mountain? Answer: From sea-level it would be 8133 m/s (18,136 mph) and from Mt Everest it would be 8121.99 m/s (18,112 mph)

We do.
Anyone can point a laser at the reflectors we left there.
Anyone.
Now.
...mirrors can be deposited by unmanned landing craft ...
...I want to see photographs of the technical artifacts of LEMs and the Rovers....
...why is that so hard to produce?
It isn't. I recently saw on the internet a telephoto of the landing site and upon sufficient zooming, one could see the LEM still sitting there.
...I would so love to see this photograph...
...please forward me a link to it when you find time to....

Also, going to the moon requires far more energy and resources than low earth orbit. You need to reach escape velocity to get to the moon, and carry enough fuel to achieve orbit and maneuver once you get there. https://rjallain.medium.com/calculating-the-speed-to-get-to-low-earth-orbit-and-other-calculations-c4df88f4cd2e
