I feel that destroying a musical instrument is something akin to murder.
I really do - I'm not making this up. It bothers me greatly to see any musical instrument smashed. I feel like the instrument maker and each person who plays it infuses the instrument with a small part of their own "souls", and this amalgam of souls in the instrument, while not sentient, is still something sacred that shouldn't just be destroyed for no reason.
Now, because I realize that these feelings have no rational basis,
But you've explained a basis of rationality that you said works for you. Something you are not making up. Perhaps there are others who agree with you, and who can see reason to 'save the instruments.' Thus, holding a position that is 'pro instrument' wouldn't be irrational.
And if we ever live in a world where life (great condition) of an instrument is dependent on the inner physical connections between a human and an instrument, I might join you in this pro instrument stance you are alluding to. It would not be irrational to me if such a connection presented itself, and there was what appeared a strong likelihood that we could see soul from instrument after it is birthed from humans. We might not see that soul while in the human body that houses it, but if say 100% of the cases that birth these instruments showed souls, I'm feeling quite confident that I would join your position, and call it rational.
I set them aside and would never dream of using them as the basis for any sort of restriction on anyone else.
If you are serious about your claim, I don't see why you wouldn't entertain idea that people ought not to destroy their instruments when there are people like you who would gladly take them and find a home. Perhaps here in hypothetical land where reality is you might just be making up your allegiance to instruments, the fact may be you don't care what people do with them, which also would have basis for rationality. But I really could see world where if say 1000 people agreed with this position, it could be some kind of law, say misdemeanor where a person who willingly destroys an instrument is faced with substantial fine. And they, like all people, are given opportunity to keep and nurture that instrument (taught how this works) or provided means to give instrument to those who would love and care for it (taught how to go about process of transferring).
However, since we've decided that our personal feelings (and just our personal feelings, apparently) are a valid basis for legal restrictions on anyone, how should we express my feelings in law?
Again, if person is seen or able to be shown (proven) as one who willingly destroyed an otherwise well working instrument, they would face misdemeanor charges either at state and/or federal level.
How long a prison sentence should we give to a rock musician who smashes his guitar?
Good question. I would say given the publicity of this violent act, in lieu of the existing misdemeanor, I'd go with 60 days in jail, or 1 year's revenue, or up to $250,000. Up to judge to decide which is most appropriate given particulars of the case.
Should Pete Townshend - that unrepentant serial offender - get the death penalty?
Guess we can't make it retroactive, but if Pete does it again in place where this is the law, I say 1 year's revenue would be sufficient lesson for him to realize the consequences of his actions. Teach him and others who think what Pete did was okay.
