The problem isn't landfills; it's the toxic substances being spread all over our planet, as seen in the video. Just stop telling people that e-waste is being recycled—it's mostly a lie.
But i can answer you the "guilt-free" part it's really easy:
Don't buy stuff you don't need, or stuff that's just for short-time-fun (Labubu vs. Guitar) ;)
What if you want a Labubu (whatever that is) more than I want a guitar? Clearly we strictly need neither of these things. It would be better to use a more objective measure like mass.
