Good ones still last a long time. What fails is generally not the LED itself but the cheap-ass rectifier in a cheap-ass case that is optimised for production price instead of heat dissipation. The fixture can also be an issue as nobody designed for heat dissipation in the days of incandescent bulbs, you might be baking those poor capacitors.

And those kinds of bulbs will stay available because there's plenty of commercial users doing their due diligence on life-time costs. Washing machines, fridges? Yes, those too, though commercial ones aren't necessarily cheap. Want a solid pair of pants? Ask a construction crew what they're wearing.
