Nonsense.
Giving people choice does not mean opening the floodgates to malware. You can disable sideloading apps by default, but also enable them upon explicit user request. You can call it a "I'm a responsible adult" button.
You don't need walled gardens for this. A sensible safe default with a pathway to disabling it is sufficient.
You can't restrict choice for everyone just because a couple of tech-illiterate folks might make bad choices. It's silly and soon also illegal.
