ELI5: Why is it that the majority of sinks dispense aerated bubbly water rather than a smooth uninterrupted stream? Is this done on purpose? If so why?

Yes it's done on purpose, the tap of your sink has an aerator on it.  If you look at it from below, you can see the little mesh screen, and you can unscrew it if you really want to.  It's in place to reduce the amount of water you use because you will almost never need a solid column of water.  It also helps to keep the water from splashing all over the place or coming out at weird angles.
