Mining empty blocks is not fraud.

If you want to use terms like "honest miners" and "fraud", please define them so we can at least be on the same page.

Only if you rely on SPV.

No, you rely on miners honesty even if you run a full node. This is in the white paper. A dishonest miner majority can commit fraud against you, they can mine only empty blocks, they can do various other things that render your money worthless.
