Yeah, the packages with aristocrat and nobility titles that gives you domains to manage aren't available anymore, though those interested can still grab a settlement during the reverse auction after DSS. A title comes with weekly responsibilities, but you can probably delegate most, if not all of them.
However, since you are interested in adventuring then you should know that your EP isn't restricted to land and stationary property. There are wagon options that does act like a mobile home, like the Vardo Wagon, which might be a good alternative if you don't want to get tied down anywhere. You'll see what your options are when the exposition store becomes available.
