Subversive broad beans

The photo is of rare purple flowering broad beans. The variety was once fairly common but is now rare. EU regulations don't help. To try and ensure consistency of quality of seed, all seed types have to be categorised and checked.
Because these beans are rare it means it's not worth anyone's time & money to get them categorised, which means that the seeds can't legally be sold in the EU, which means they get rarer, which means....
But I can keep beans from this year's plants and use them next year. And I can give them away.
Whoever thought growing beans would be subversive?
