OPs whole shit is wrong, honestly. I have a house furnished on quite a lot of Ikea shit that's been going strong for 10ish years through multiple moves? Though I don't disagree that I'd rather have better materials like real wood that can be refinished and really can last a century, that is not happening for anywhere near Ikea prices.
Sometimes on Facebook Marketplace, Craigslist, or similar. If you like mid-century modern, and are willing to reupholster, you can often find 50 year old pieces at estate sales and such. But new? Ain't happening.
