I'm wondering. Can any compact subset of $\mathbb{R^2}$ be written as a suitable IFS attractor?
Can someone explain? Thank you for visiting my question.

In general the answer is no; they prove it not just for the plane, but for any uncountable Polish space. I haven't read the paper, so I'm not sure EXACTLY where the result is:

This paper discusses the result, as well as generalizations of the question to infinite IFS's:

There are some positive results; in the paper above, they prove it for certain sets containing clopen copies of the Cantor Set. It's also known for polyhedra in $\mathbb{R}^n$.
