It can. For example, instead of buying bottled water or olive oil or vinegar at a few grocery stores near me, you can bring in your own bottle and fill up.
Instead of buying pre-cut veggies and fruit, you can get the individual ones and do it yourself.
Unfortunately, what this thread sees as waste consumers often see as a benefit: buying items in sealed containers lets you have peace of mind against spoilage or in-store contamination (anyone can open up those pour-your-own tubs of olive oil and sneeze into them).
Additionally, packaged things stack up better, so you can offer consumers a wider variety- laundry detergent scents, drink flavors, and so forth. Offering pour-your-own means maintaining and cleaning goods and equipment that are exposed to both product and air, which is more expensive for grocers.
Finally, packaging (especially the clamshell variety) is often used for protection- from damaging the contents in shipping / handling to acting as a mild anti-theft device.
So, yes, there is a market for reduced-production goods. Produce, grains, soft drinks at gas stations, and some other goods are already there.
If there is a reasonable way to protect goods, ensure their freshness, offer a unique variety in a low maintenance fashion, there's money to be made. If you can't do that and still want to reduce production, you're going to either end up creating more waste through some side effect of the tradeoffs involved.
