Well, that could have been fixed by booting from an usb stick, chrooting into you real system and either downloading and (re)installing the python package this way, or, if your package manager depends on python, download the package in the Live Linux and extracting the python package into your system, and then reinstalling it, so the package management overwrites your “manual installation”.
Could be tedious, but less so that having to reinstall everything IMO.
I really hate most subscriptions, because the prices are often too high, they rely on locking stuff behind paywalls, instead of providing a good service.
Here is the difference, I am ok paying monthly for storage space, servers, and hosted/managed open source web services, because there is competition and standard interfaces there. They do not hold you (or your data) hostage to their service, what they provide is good on its own.
For example, if GOG invests money into writing open source libraries, apps and APIs to efficiently and easily share save games between devices. Let people self host the open source backend, but offer up a subscription for a managed instance, with maybe some voting rights for new features or support for games/platforms to be integrated into the open source front & backend, then I would be willing to support this.
And other stuff like this.
Use subscriptions to offer good services, which also allow you to improve the whole ecosystem, while also not putting yourself as the gatekeeper, and locking people into their service.
