Firstly, I don't think that its ever going to happen, secondly if it was to happen, it would have to be in a situation when the S had already hit the F in a major way and we were already on the verge of riots and the like. Thirdly, there is already a bit of a crackdown starting on wasted food which if taken to its logical conclusion will mean that there will be more food in circulation, possibly lowered food prices and the like. Fourthly, the likelihood of you having enough food stored up to last you for years is very thin, and even if you did have 12 months of food in store, you wouldn't see that as excessive anyway as it is the way that you are going to stay alive for that 12 month period.
One could in a rather
paranoid way assume that the Nation is preparing itself legally through statute or similar instruments for a situation in which there may be diminished food supplies and we are in a SHTF situation, but again, considering the wealthy and powerful need to keep the patient alive in order to carry on sucking its blood, the likelihood of us ever entering in that situation in the UK is remarkably slim.
As with all things, think about what you are preparing for and not what dubious media sources are telling you to prepare for.
Unemployment, times of illness and issues with power and / or water security are hard enough to prepare for, let alone TEOTWAWKI.
