Your statement that 'Vertical farming for non-vegetables (or fruits) is likely dead-on-pitch.' is true with current technology. But there have been significant developments in this space in the last few years. See this work done by Zach Lippman at CSHL. https://pubmed.ncbi.nlm.nih.gov/31873217/ https://pubmed.ncbi.nlm.nih.gov/31873217/ Early flowering, dwarf varieties such as those described along with renewable energy (thinking of electricity rates going negative in Germany recently) may significantly shift the economic viability of growing fruits indoors.
