Is it possible to have real-time live-feed of the entire planet? If cost isn't an issue, would something like that be possible?
The short answer is no. High-resolution imagery comes from low-orbit satellites, which make a complete orbit about every two hours, and image long, narrow strips with each pass, taking days to image the whole planet. There are many of these satellites: commercial, non-military (publicly-accessible) governmental, and governmental (secret), of varying resolutions. These are also supplemented by aerial (plane) imagery.…
Organizations/NGOs heavily rely on satellite imagery (i) to assist in delivering many humanitarian efforts. It would seem useful for the UN to strongly prohibit the diminishing of such capability. (i) www.hotosm.org

The resolution and angles for your point of interest will change but you should be able to keep a near-constant coverage.

In addition to cost, there are various national laws that restrict satellite imagery with resolution better than various thresholds.
Which the article indicates, at least as it relates to the US and her companies, is no longer the case: > In July 2020, the KBA was dropped, and now the US government allows American companies to provide far higher-quality images of the region (so that objects the size of a person can be readily picked out).

planet.com can get you a ~12 images per day [1] for a reasonable price. If cost really isn't an issue, I'm confident you could strike a deal with planet.com to place their next few new satellites into the specific orbit you want to up the frequency even more.

That's one such agreement between two governments; there are numerous other laws and agreements that would impact anyone attempting to provide real-time imagery of substantial portions of Earth.

So that means most of the south and north part of the earth cannot be covered with such a constellation; they would need to be orbiting satellites, which makes "real time" even harder, because it would require an enormously complex choreography to ensure there's at least one satellite covering each square meter, at all times.
