Cool Skyscraper idea- Metropolitian series

This post is part of the city series. I think that we have developed by spreading out rather than vertical construction. However, urbanization has some benefits. For instance, if the whole U.S population could be packed into a small area, comfortably, we could take advantage of many benefits. For instance, we could have more farm-land, a lot/a gigantic ton of forests, clean rivers, high biodiversity/wild life regions. One of the key steps is designing a structure that can handle the load.

The proposed idea addresses to solve many problems:

1): There are enough elevators to transport 100,000 people. This is solved by having interior large exterior elevator hubs (to save space). There are multiple hubs. Each hub contains 30 stage elevators. Assuming each stage elevator can hold 40 people; it should meet demands. Also they would not take up a lot of real estate, only 3000sqft. The way it works is if I want to get into building A, but the elevators are on high demand, I can take the elevators in building C and walk on the brown skylines and through the blue horizontal rectangles to get to A. Also, these elevators are electromagnetic levitating and can reach speeds of hundreds of miles per hour which would transport people very quickly. In addition, the elevators are at different sizes in the hubs. A group of 10 people are forced to take a small elevator rather than a large stage elevator to handle rush hour loads (9:00 work, 5:00 coming home etc). There is also software that can work out the most efficient ways to travel.

2): The towers can handle massive loads. Since this is google draw and not a CAD software, I am restricted to what I can draw. However, the actual towers would employ many features to reach massive heights. For instance, the towers would break at multiple locations to prevent air vortices. There would be a lot of X bracing/Truss beams. The towers also are braced together as seen (to handle hurricanes,...). I could also imagine technological advances being developed like a new steel beam that is 10x as strong.

3): Each tower can be somewhat self sufficient: Each tower will have a wind turbine on the roof and a solar panel system on the windows/elevator hubs. It cannot power the whole tower, but it helps. It can also collect rain-water and purify it via RO.

4): People can enjoy Nature: On the lower levels, there will be forests. On the upper levels, greenhouses, aquariums, swamps, etc are built on top of the recreation/sky-walk buildings.

5): Pack at least 70,000 people in a 4-10 acre lot. Let's say the tower is 7000 ft. At 10 ft/floor, that is 700 floors. If each floor is 10,000 square feet and each family gets a generous 2000 sq-ft. Each floor houses 5 family units (10,000/2000=5) which means at least 20 people/floor. That is 14,000 people per building (700 x 20) and each person gets a generous 500 sq ft of living space. That is 70,000 people per complex (14,000 x 5 towers) and each complex may have different specifications which allows the population to be 100K+. Also it has a low footprint.
