\protect is not a good idea. There is a reason why LaTeX refuses
footnotes in titles - titles can appear in multiple places in the
document (TOC, page footer, etc) and thus references to the footnotes
are non-deterministic.

https://texfaq.org/FAQ-ftnsect suggests to use
or to pass optional argument to \section without footnote
\section[title]{title\footnote{title ftnt}}

The footmisc package is a nice solution, but it has certain requirements
about loading order. In particular, it must be loaded after certain
packages (setspace, memoir). We cannot yet control the \usepackage
ordering in LaTeX preamble and always place default LaTeX packages first
- something we cannot do for footmisc.

The \section[...]{...} approach may work, but it is tricky - it is
completely up to the `org-latex-classes'. So, we may have to use regexp
replacement, which might be fragile.

So, I prefer the first approach with footmisc. But we can only do it
after Timothy's patch introducing more flexible templating system is

CCing Timothy.
