Some purely technological problems are hard to solve. There is already a market for (very expensive) meat substitutes and they taste like crap. If you are talking about some sci-fi "replicator" tech that will just "synthesize" you and avocado, then I'm not sure how achievable that is in short or medium-term irrespective to energy prices.

Much better for whom? OP said they like "nice things". I would also prefer avocados to spaceships since I'm not that interested in space travel without FTL.
