That may seem like a lot of ice, and a lot of weight, but in relation to the volume of the Earth it's not a lot.

Consider that the oceans comprise about 0.1% of the volume of the Earth, and that there is no evidence that at any point the oceans were completely frozen. That is, unless you include the Pre-Cambrian "Snowball Earth" theory; and I suspect the Pre-Cambrian may be a bit far in the past for your liking.

Another consideration here is that the oceans form part of the crust, as did the ice, so the phase change from water to ice is not going to add weight to the crust. The transfer of water from the oceans to ice on the land caused isostatic readjustment, but that would not involve the sort of movement that would increase friction in the transition zone.

There never was nothing.
