Yeah, and that is the point. All user's programs including curl, wget, the web browser, anything else that connects to the network run as the user, and all the user's programs, by default, have access to everything inside ${HOME}.
Most people don't really care if /bin gets obliterated, but they do care dearly when /home/joe/photos/annies-2nd-birthday gets wiped.
Backups FTW.
Just make another user bro. If you can't even create a user to run a program you distrust, the issue is not that windows doesn't provide sandboxes, it's that you don't use them
And no, it's not "a lot of work" it's the bare minimum
Protecting a user from himself is hard. Protecting user from others is easy. Linux is influenced by unix and a lot of installations are servers. Where most programs run under their own accounts.
You can always have two user accounts: oblio and unsafe-oblio anf have a shared folder between the two for transferring files. Or invest into some backup software.
