Obviously, I would not be OK with missing the playoffs. I don't think there's any danger of that. Even if everything were to go to I can't see us being worse than 7th or 8th and I think a healthy Spurs team can beat Golden State, Memphis or Portland without home court. Obviously, it would be better to be a high seed, but it's not the end of the world. OKC and maybe Dallas are the only teams I'd really fear if we didn't have home court.
And if we were 8th and OKC 7th, then they'd be on the opposite side of the WC bracket. We wouldn't have to worry about them until the Conference finals. A lot can happen on the way.
