There's a lot more nuance here and that video is misleading in several ways. Starting with the weakest reason first, but one that's also very important. Space is really big. There are some 6 figures of tiny things in space and thousands of larger things. This sounds pretty scary. But now imagine that we put 6 figures of tiny things, and some thousands of large things in random places in the US and set them on a random path. You can intuit that the odds of any collision are going to be extremely low. And now imagine the entirety of LEO. It is magnitudes larger than the USA of course. The next is that objects tend to be going in the same direction. Rockets take advantage of Earth's rotation to get a 'head start' on their launch which means that most things end up going in the same orbital direction. Two things going the same speed with the same orbital characteristics will never collide. With different orbital characteristics, they will get two chances for collision per orbit with an extremely low chance of it occurring by chance. And maybe the biggest point is another really cool and counter intuitive part of space. When we think of the USA we obviously just think of the ground. But of course there is a vertical axis in space. And the awesome thing here is what determines your altitude in space. It's entirely based on your velocity (well and the mass of whatever you're orbiting). In other words, objects cannot collide unless they're traveling at the same rate of speed. Pretty neat! Another issue is that even at LEO, objects do experience some atmospheric drag. Any object in LEO that is not occasionally correcting its orbit (accelerating) will eventually come back down to Earth. This includes all of that tiny debris. So now make the US absurdly vastly larger. And create multiple layers of the USA where any given car traveling at any given speed goes on a specific layer. And set them [almost] all in the same direction. And finally remove small stuff (or 'decommissioned' cars) over time. So sure, space debris is something to definitely keep in mind - but I think people don't really realize how relatively irrelevant this is. Another thing is that even if we did experience some catastrophic kessler syndrome level event it would mostly have no impact on things going through LEO (and not orbiting within it) simply because the massiveness of space just means the odds of an impact are so very low. So it would not kill space travel as the video states. And lastly, necessity is the mother of all invention. There are an enormous number of viable ideas for removing debris from space. But there hasn't been that much of a push for them simply because it's not really necessary yet. If we reach a point when it becomes necessary, there are solutions. So issue? Sure. "Massive" issue. Nah.
