Given the Moon's mass is 7.3477×1022; and a "cable" made of carbon nanotubes with a tensile strength of 63 gigapascals would need to have a diameter of 4000km in order to endure the tension of that mass -- and that's ignoring the mass of the cable itself ~185 trillion tonnes -- I'll wait until someone works out how to manufacture the 4000km diameter x 400000km cable and finds a source of energy on earth sufficient to lift it into space before I start worrying about the consequences of doing this :)

The Moon and the Earth are already roped together—gravitationally. And we know what that means.
I gather the question is if another, physical tether were attached to both. It'd most likely have a healthy amount of slack to account for the elliptical orbit. Perhaps a counterweight is in order at some intermediate point to provide tension. In any case, the rope would have to endure its own weight only (which is still quite a task!), plus some for doing useful work.
Let's suppose we have a rope with more than 10% elasticity (relative delta of distance)
The earth is always visible from the near side of the moon (that's the other half from what people erroneously call the "dark" side).
If the moon was always visible from one of the poles (like the sun is for almost half a year) you'd only need to compensate approximately 360°/24h (the moons orbital rotation of 360°/month doesn't matter much) with something like a slowly rotating swivel.
But that's never the case, I suppose the moon is at best only visible for 18 days in a row IIRC.
So you'd end up constructing a large tower in Antarctica, such that from top the moon is always over the horizon.
No idea how tall this tower must be, but if it crosses the atmosphere (I'm pretty sure it must¹) this would also solve the problem of a giant whip lashing thru air.
All the construction problems aside, I wouldn't be surprised about electrostatic problems arising from connecting two giant bodies.
Can't see the benefit of such a construction, that's at best a theoretical question for math class.
It's hard to pick just one... Cheese manufacturers would go bankrupt because cheese would now be free. General interest in rope and rope technology would get a significant boost. Conspiracy theorists would claim that the earth and moon have not actually been tied together, it's all a lie. Religious groups would find new and interesting reasons to harass and kill innocent people, especially those who supports the idea of tethering the earth and moon together because various religious texts clearly warn that this heralds the end of times. Several people would try to climb the rope and get themself killed in new and hilarious ways (not limited to fatal rope burns). An unprecedented amount of lawsuits would ensue.
The one thing in favor of this scheme is the unequal distribution of mass in the Moon keeps one side always facing the Earth. But it does not stay over the same point on the Earth, so a physical connection would not be possible or even desirable.
The solution is to anchor a rope to the surface of the Moon, but cut it a few feet short of the distance to the Earth's surface. The Earth end of the rope can move freely as the Moon orbits. Then, when you want to get to the Moon without a rocket, you just need to grab the end of the rope as it goes by.
We Americans are more impatient, so I liked the idea that I could get in my private jet and fly to a convenient spot just ahead of the rope's path. No need to wait those pesky 27 days! But your multiple ropes idea is sheer genius.
