I'm more optimistic about motivations. Most people don't have time to sell (or even give away) something they bought for $200 now worth $30 on the second-hand market. If I could dispose of this stuff safely, freely, and easily, I definitely would.
Heck, if Ikea keeps this up, I bet there will be a third-hand market where people haul this junk away to Ikea, and resell vouchers/new furniture. That'd be awesome. If I could dump this stuff on the curb, and know it won't end up in a landfill, I'd totally do it.
