Is it possible to allow sideloading and keep users safe?

> Are you allowed to run whatever computer program you want on the hardware you own?

Yes. It is a basic human right.

> This is a question where freedom, practicality, and reality all collide into a mess.

No; it isn't. The answer is clear and not messy. If you are not allowed to run programs of your choice, then it is not your hardware. Practicality and "reality" (whatever that means) are irrelevant issues here.

Maybe you prefer to use hardware that is not yours, but that is a different question.

Says who?

What's your philosophical argument in favour of this?

It's directly in the text.

> hardware you own

That's not an argument.

Please explain how owning an item of hardware implies that running whatever computer program you want on it is a basic human right.

If there are rooms in your house someone else could lock you out of, do you own the house or do they?

If someone else could use your car without your permission, do you own the car or do they?

If someone could grow their own plants in you back yard, do you own the garden or do they?

If someone else could choose what programs run on your computer, do you own the computer or do they?

Saying "basic human right" instead of just "basic right" may be odd, but definitionally, owning a thing means having the right to say how it is used. Either you own it and have that right, or you don't own it and don't have that right. That's what owning means.

There are parts of your car that you are not legally allowed to remove or disable (for example, the muffler or catalytic converter https://19january2017snapshot.epa.gov/sites/production/files... ).

There are times when it is necessary to limit the rights that a individual has so that the system that the individual lives within can work.

You can buy a radio transmitter, but you're not allowed to operate it without a license. You can likewise buy a car, but you aren't allowed to operate that either without a license.

You do not have the right to modify your phone so that it acts as a radio frequency jammer.

Possession of a device does not give an individual unrestricted rights to what can be done with it.
