I'm actually amazed to hear someone say this. Maybe you only travel alone, like middle seats, and are always first to board?

Every time I accidentally fly Southwest, I'm horrified at how bad the boarding system is. People plop down wherever leaving one-seat holes so you can't sit with your partner.

It also guarantees more seat trading than an assigned system because most people in the assigned system have seats they wanted. People on Southwest flights are always haggling so they can sit with their partner. I almost never see seat trading on other flights.

My mind is blown. But then again every time I take a Southwest flight, I'm wondering "who tf is this for?" and I've finally found my guy.
