I'd play purebaseball over fantasy even if half the teams were inactive. So what. The robot sets good away lineups, plays home games, etc. You usually can't even tell when you are playing a team without an owner. I've seen an ownerless team make the playoffs. So what if you can't trade with them. Most teams only make 1 or 2 trades a year anyways. Some owners have never made a trade.

Yes, having every team with an owner would be great, but it doesn't affect the way you run your team (at least is hasn't affected any of mine, and I've played for 7 years with many teams).
