Last time I looked satellite measurements showed 3.2 mm/year, while
historical tide gage measurements averaged 1.7 mm/year. These are
subject to long term drift because the land rises and
falls. The satellites were calibrated with only a subset of the
tide gage data. This means that the long term drift in the
satellite data is different from the long term drift in the tide
gages.

It is wrong to plot the earlier tide gage measurements on the same chart
with the satellite data without making this clear, but this kind of
misrepresentation seems to be usual for the AGW crowd. Neither
satellite data nor tide gage measurements show any acceleration in themselves.
It is only when you plot them on the same graph that the appearance of
acceleration is given.

The satellite rate of 3.2 mm per year seems to be holding steady or
even declining a bit. This works out to be one foot per century. In
2000 years we could have a real problem.

You don't know what you are talking about, no cites.

There are also geologic sea level records, they proof that in the last
2000 years the sea level changed by about 10 cm/century up to 1850.

The IPCC report has a section on this.
