Our former 2 year-old and current two year-old have neither choked on their marbles. Why? Supervision. You play with your kids and then you can stop them doing stupid things that are going to cause them high-level harm.
The hard part I find is letting them hurt themselves as part of their learning.
Indeed our 2 year-old just used a kitchen knife (about as long as his forearm) for the first time a couple of weeks ago to chop the potatoes he peeled. Close supervision.
"He could swallow a marble", well yes, he could bash his brother's head in with the corner of an iPad, get hit by a meteorite, run in to a wall, drown himself in the toilet, etc..
