People have no effective representation now. This is not going to get any better.
Term limits reduce the amount that the politicians can steal during their time in office.
You bring up a valid point about the power of the permanent Government bureaucracy. The "Deep State" people are the ones that actually elect the politicians. Government employees should be term-limited as well as reduced in numbers.

While you're at it, how about banning the insider trading practices...eliminate their ability to generate incredible wealth using information the rest of us aren't privy to.
How about election day after tax day?
Printing parts of constitution on the back of the money.
