^^^ The only reason industrial got so dense in the first place was that our cities and economy required it. Large trucks and modern logistics didn't exist yet. People still walked to work or took mass transit. Most goods were transferred by hand to railroad cars. Denser industrial development meant greater efficiencies. As industry has become more and more automated and modular, the advantages to being spread out have greatly increased.

More room to work in has always been an advantage for industry, it just wasn't really an option in the past.
