Let’s pretend for a second that the TSA is not a circus meant to appease people that are not paying too much attention being performed by an organisation that’s effectively an employer of last resort.
The TSA will not even stop people from taking what they would need to make a Molotov cocktail with what they can buy in the airport shop. Their stated goal is not to reduce the risk of incidents to 0 is reducing it to reasonable level with the least disruption to the air travelers as possible - otherwise they would be trying to get people to fly naked and without luggage.
Saving money on food to buy a guillotine is personal finance.
