The public goods the government provides suffer from a free-rider problem.

Answer 1

Correct answer: "The public goods the government provides suffer from a free-rider problem."

Why: Many government services (national defense, street lighting, lighthouses, basic research, etc.) are non‑excludable and/or non‑rivalrous. Because people can benefit whether or not they pay, voluntary contributions typically underprovide those goods — individuals have an incentive to "free ride." Compulsory taxation ensures enough resources are collected to provide and maintain public goods at the socially efficient level.

The other items you listed are complaints or consequences (political opposition to transfer payments or higher rates, or waste from costly contracts), not reasons why coercive tax collection is necessary.
