I expect that the figure you provide is wild speculation on someone's part, but footprints would most likely be destroyed either by an asteroid or comet striking the moon or a moonquake.
The footprints will stay on the moon because there is no weather or atmosphere on the moon! That means that if there is no weather there will be no wind to carry it away or sand to top over the footprints!
There is no erosion on the moon surface because there is no wind or water to flow over the landscape. So, the footprints have nothing to disturb them and will remain as long as the moon remains.
there are not footprints on the moon the ground is very solid
Moon has no atmosphere and dusty footprints remain on the moon forever, So there is no wind at all.
Well, on the moon, there isn't an atmosphere which makes weather. Without any weather, wind, flowing water, etc, there's nothing to erase the footprints unless a meteorite hits it. And again, without an atmosphere, there's nothing to slow down the meteorites, so it pounds the moon at full speed, leaving a huge crater that sometimes stretches many miles. Thanks to this, footprints can stay there for millions of years.
In 7,000 years
Ten Million Years
Because there's no gravity or wind.
Well it probably depends on the space boots are heavy, but about millions of years.

I recall during the moon walks that the footprints were expected to survive for thousands of years; so yes.
because there is no erosion on the moon because it does not rain
Until something disturbs it, like a future meteor impact, or a future moon landing. The footprints left by the astronauts may last millions of years.
Oh yes the footprints left on the moon by the astronauts , will remain there for years or centuries. The reason is that there is no wind on the moon surface. So there is no chance of dust covering those footprints.
The footprints on the moon left by the astronauts will still be there in a few thousand years. They will eventually be covered with new dust from micrometeorites.
There is no wind, and barely any gravity so the footprints will stay on the moon for yyyyyeeeeaaaarrrrrrsssss.
