There's no enabling here in the usual sense of the word, they just made it cheaper. It'd be like a headline "copious butter enables little Tommy to eat vegetables". Apple could have repatriated that money at any time, and likely would have if they didn't know that they could hold out for a feckless Republican administration to give them a big tax holiday. Pretending otherwise is a fiction that supports repeated corporate tax rate reductions and encourages companies like Apple to make use of elaborate tax avoidance schemes.
Alternate headline: Trump policies take American companies closer to the globalized ideal they always envisioned, by making the American market just another market they are not tied in any significant way to. $29 billion is spit in the bucket of the deficit created by this bill, and Apple is the biggest market cap company in the world, with the biggest overseas reserves.
A headline that will never see the light of day.
Mainly because it's hard to suppress laughter if you think about it at all beyond a surface level. See discussion in another thread. I don't want to repeat myself.
