No, I think you are confusing the two kinds of trusts: a revocable trust means you still own the money or property, an irrevocable trust means you don’t own it anymore. Either you “give it away” in an irrevocable trust (which can’t be “dissolved”), or you don’t give it away (in a revocable trust).
You are describing putting something in a revocable trust, which is not spending it or giving it away. It’s closer to just putting a label on it: “this money is for charity”. You don’t get a tax deduction unless you put the money in a irrevocable charitable trust or the charity actually receives the money (from any source, trust, whatever).
Uh… fingers are not a good type of infrastructure.
