I do believe that consumers would pay a premium for incandescents up to a point, though. If someone had one or two lamps they specifically wanted to use incandescents in, for example, they would probably justify paying $5 or more for a high quality bulb. While expensive, it would be roughly an annual expenditure and not enough to impact most people's budgets.
Specialty stores here are still coasting on the old stock incandescents. You can literally walk to the specialty stores in Amsterdam or Den Haag and walk out with an entire backpack full of standard incandescents.
But clearly, people aren't really doing that a whole lot becuase the stocks still haven't depleted and we're more than 10 years after the ban of import and production of incandescents in the netherlands.
Alternatively, all thrift shops have bins full of both new and used lamps of all types. I sometimes see people dig up incandescents. Apparently those people really want them, but also they will just keep buying them there for €0,50 to €1 for as long as people keep bringing in NOS incandescents to the thrift shop. As for their motives - i have no clue if they really specifically look for incandescent light, or that they are completely ignorant about the differences and just buy them out of habit, or whether they need them for dim bulb limiters like i do.
It will take another decade or so (hell, maybe even more) to actually deplete existing stock, so only then super expensive new production won't face the competition from cheap, sunk cost/written off old stock.
Any peron caring about light quality today will likely sooner buy a 94 CRI led (the Ledvance thing i have is definitely good) than deal with the fact that modern fixtures are usually not designed for more than 25w of thermal energy, conciously buy older fixtures that still have heat resistant sockets etc.
Maybe in 50 years time, when stocks have properly dropped to the level of individual NOS lamps' prices rising to 50 euro a piece, that it will be possible to restart a small scale production system, like they're currently doing with bright emitter vacuum tubes:
https://brimaruk.com/product/ediswan-type-r/ or like Dalimar is doing with brand new Nixie tubes.
But it will be a considerable amount of manual labor, and you'll be looking at cost closer to 50 euro than 5 euro per lamp.
Getting an automated production line up and running will be at least 2 million euro just to fix everything in the production line (just getting 'stiff' mechanisms, iffy limit switches and old computer control systems working again) and re-line the glass furnaces and stuff. Double or triple that if you have to strip out the tons of asbestos from legacy production facilities. Philips' glass furnaces are still around and have not been demolished yet. It wouldn't surprise me if that's becasue the furnaces are absolutely filled with asbestos and they're hoping the company's remains switch owners often enough for the national government to lose track and the cost for cleaning up the mess just goes to the tax payer...
More likely is that this will just happen in China, though even China doesn't seem to be bothered with producing incandescent lamps anymore. India maybe?
