It could ? It would ? It should ?

I am pretty sure the seabed under the tower will settle much like the sand under that famous bell tower in Pisa.

@Slowburn
I am pretty sure the designers thought of that.

All these ocean based wind farms are missing a good source of energy. The wind should be only one part of the energy mix. They should have a turbine under the surface to harvest the power of the ocean currents and the waves.

Stanford's Mark Jacobson is putting forward a plan to power the world economy fully with wind, water and solar (WWS) by 2050 with http://thesolutionsproject.org Advances like these make this approach ever more feasible. More data on US and worldwide implementations are here: http://www.stanford.edu/group/efmh/jacobson/Articles/I/WWS-50-USState-plans.html

You can partly integrate the power generation of these windfarms with pumping water up a hydro-electric dam during times where not a lot of power is needed (i.e. at night). During the day, you can use the stored energy of the water to run the hydroelectric dam at a total efficiency of 80%. This partly solves the intermittent power source problem of winds, thanks to the fast response time of dams to adjust their generated power.
Unfortunately, the hydro electric dam capacity in the developed world has reached a stadium where there isn't a lot of room to expand. Not to mention the local region impact of building one.

Pumped storage is effective if done properly and there is a place it can be constructed. For the good and bad sides of this see :

Not long after it was built some friends and I were bicycling in the area and rode our bicycles up the mountain and around the reservoir. We had no idea what it was and had a lot of fanciful theories. When we got to the end of the road that went most of the way around it we had to climb up to the top of the wall to see what it was all about. And being downwind on a very windy day got a face full of spray. We each had to have a look for ourselves. Finding a big lake on the top of a mountain. is not something you would expect. It took a while to decide what it was for as we had never heard of doing something like this.

Joe Hockey was horribly quoted out-of-context by a dimwitted reporter - he was offended by the financial unsustainability of wind farms, not their aesthetics (bloody obvious - he's our Treasurer, how the heck the idiot reporter who heard him talk failed to grock what he said continues to amaze me).
If you watch the interview (or pull out your calculator and do some basic maths), you'll find that coal is *way* cheaper.
And, before you get started on CO2 arguments, show me how you plan to convince everyone in the developing world to stop cooking, or all industrial peoples to stop making stuff, first. We're stuck on a rock with 7.1+billion people screwing it up, and there's not a licking thing anyone can do to stop it.
Yes - YOU can make a difference, and windfarms will help, but no, nobody will ever notice what difference you or windfarms will actually make, because it's nothing more than a drop in the ocean.

Freddy there are a lot of existing dams that are rarely if ever full - eg. Lake Mead (Hoover Dam) hasn't been full for over 30 years and with climate change on top of fresh water demand that is looking likely to remain the norm rather than the exception
So there is considerable capacity within the existing infrastructure for pump up hydro.

Christopher, apart from indirectly calling Alan Jones a "dimwitted reporter" (hard to disagree, although real reporters should take offense) , Hockey is on record on his own web site, and there is nothing out of context about it. Jones was trying on his tired old denier spiel but clear as day, Hockey just thinks the wind farms spoil his chauffeured drive to work;
