That is the problem, though. It was never yours. It belonged to app developers, some of them potentially nefarious. When you have thousands of packages supporting your desktop environment, the only sane security model is to treat everything like a threat, and make permissions opt-in, not opt-out. X for example just lets every program spy on your keyboard input, sample memory /framebuffers, etc.

In the end, when it comes to security, the average user doesn't know best and should let the people who do design the systems. This is why we have seatbelt and child endangerment laws.

But it has been mine for decades and nefarious developers somehow weren't a real issue in my distro's repositories for this whole time. It's a self-inflicted problem.
