> Also, "a few years" is a long time between deciding you want fruit and getting to eat it.

The best time to plant was a few years ago, the next-best time to plant is today.

This feels like a weird argument; you can decide you want to grow your own fruit today, plant that tree, and continue to buy fruit for the next few years until it's ready. This isn't rocket science. For most people it's not particularly likely that they're going to decide in the next few years that they don't like apples or lemons or whatever anymore.

Your lack of desire to either plan ahead or be patient doesn't invalidate the approach.
