Body autonomy is objective morality by Boolean logic, and moral nihilism doesn't solve that problem

Self removal function in Boolean logic:

A = B

B = removal of A

A = removal of A

And this logic remains true in case of ability to remove autonomy.

Removing autonomy = removes ability to remove autonomy

In other words,

A = removal of A.

A self-removing principle.

So saying that

"Autonomy can be removed for subjective reasons"

When removal of autonomy = removal of ability to remove autonomy,

What follows is:

Autonomy can be removed for subjective reasons = ability to remove autonomy can be removed for subjective reasons

In other words:

A = removes ability of A

A self-destruct of principle

The moment person thinks:

"I can violate body autonomy for subjective reasons"

He is merely justifying removal of own autonomy, and with it, removal of ability to violate autonomy.

Because decisions have to be made, and those decisions require reasons. Should reason be subjective and decision as result self defeating, it is merely a self removal function.

For example, if I were to say:

I decide to remove autonomy for subjective reasons = Autonomy can be decided to be removed for subjective reasons = My own autonomy can be decided to be removed for subjective reasons.

Because any subjective reason I give, subjective reason is still subjective, and using it as reason merely logically enables same decision to be made about removal of my own autonomy.

Truth nihilism doesn't solve this, because even if we were to accept that moral statements have no truth value, the decision to do or not do something, to accept or not accept something, still has to be made.

If it is made for subjective reasons, subjective reasons can be used to deny it. Making logical decision impossible, and thus any decision person makes in that position is both self-defeating and not logical.

Likewise, saying that morality lacks truth value merely makes it impossible to justify any violation of body autonomy even further.

Because removing body autonomy due to morality which lacks truth value = removal of removal of body autonomy due to morality which lacks truth value.

Suppose someone were to say:

"Morality lacks truth value, but I will remove your autonomy for no reason."

We can merely respond with:

"Then we will remove removal of autonomy for no reason"

Removing truth value doesn't actually solve contradiction because the only way to violate body autonomy is to take some form of action to violate it. And if that action can be taken for arbitrary reasons, or for statements which lack truth value, or for no reason, same can be applied to remove that action.

Person must make decisions, and if decision is made for reason which ultimately defeats decision, that is logical self-removal of that decision.

Suppose a person wants to decide:

"I want to violate autonomy for subjective reasons"

He is saying "autonomy is to be violated for subjective reasons"

And then same decision logic ultimately says that his own autonomy is to be violated for subjective reasons, therefore removing his autonomy and ability to violate autonomy.

In Boolean logic, if function removes itself, it cannot be true.

And violation of autonomy is a self removing function.

Because there is no way to decide to violate body autonomy without same logic of that decision applying to your own autonomy.

There is no escaping that:

Removal of autonomy = removal of ability to remove autonomy

So any justification of first necessarily justifies second, and second is a removal of first.

So if person accepts that removal of autonomy is okay, he accepts that removal of removal of autonomy is okay.

There is no way to accept one principle without logically being forced to accept another, or not thinking logically at all.

And people who don't think logically aren't escaping self-defeat.

If autonomy can be removed for reasons which aren't logical, removal of that removal can likewise be made for reasons which aren't logical.

So when person wants to decide:

"I accept that violating autonomy is a decision I will make"

The logic behind it merely says that removal of his own autonomy is a decision to be made.
