You can see the process from the very beginning to the end, when you harvest vegetables containing still more seeds. It's a complete cycle of nature.

The public perceives it as undesirable. If the public perception changes, then maybe we'll change our policy.

There are several reasons for this (low number). The people who were taught to garden from seed by their parents, grandparents or teachers are more likely to garden from seed later. It requires time. You can't just sow seeds and walk away. You have to nurture that seed. Many people are too busy to start from seed and they would prefer to purchase plants.
