The 'logic' being proposed is rather breathtaking in it's vacuousness; what we're doing isn't working, so let's do nothing (basically).

I wonder if a farmer would use that method effectively when dealing with weeds, pests?

I wonder if a General would make such a call in battle?

What would happen to a person lost in the wilds or out at sea if they simply did nothing?

It seems pretty evident that while the law might be changed, related laws won't go away, regulations won't be diminished, resources won't be saved to be used for better purposes.

So perhaps it isn't the war on drugs that is the problem here.

Sometimes, the air you 'let in'matters less than the air you 'let out'.
