|Well in reality nothing will happen if IE is uninstalled.|
I can tell you've never tried this before. Perhaps things are different now in Win 7/8 but I know of many people who tried this in XP and ended up reinstalling from scratch in the long run. It's worth noting that IE is an integral part of Windows (on purpose) and if you try to remove it and don't do it correctly, you'll bork your system.
Tell me, what would be the point exactly of uninstalling IE when it's so much simpler to just not use it?
I'm sorry but, having worked in IT for almost 20 years I've come to know that KISS is the best answer in all cases and you're advising complexity when my advice is as simple as it gets.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
