I can't use Linux because it doesn't have offline installers (without hacks and workarounds), even if I were willing to ditch decades worth of engineering software, Adobe and old games.
What? You can just put the executable in your path (in simpler terms put the program where the OS will look for it). You have the install command which does that and sets some permissions. That's not a hack that's just how it works. There's also apt-offline[0] which is apt (the package manager on Debian/Ubuntu and the rest) but wait for it... offline.
Of course you will need to get the source or the executable on the machine by some method, such as a USB or whatever. But I'm pretty sure Windows or Mac can't create software out of thin air either. Can you give me an example of a workflow that you use on Windows that you would like on Linux? I'm pretty sure I can help you solve it without hacks.
If you forget what you believe "installing" software means I'm sure you can learn to appreciate Linux and maybe even see that it's simpler and easier than Windows.
I am replacing Win11 with Win10 and Win7.
