Another reason to grow heirlooms is because they breed true. Hybrids do not. You can save your heirloom seeds every year and never have to buy any more seeds or plants. With hybrids you are forced to buy new every year. This is why hybrids are pushed by nurseries and garden centers. Those centers make money from hybrids.
Have fun recycling your seeds. I have better things to do. My time is worth more than the dollar or so seeds cost. Heck, my time is worth more than the few dollars a seedling costs. I even pay more than that for one big starter plant so I can start enjoying my tomatoes the first week of July. I continue to enjoy my vine ripened tomatoes in the fall when heirlooms have succumbed to blight. I’m sure you are much happier with your memories and superior attitude.
