You have a total misunderstanding of what romantacism is. Just because tonally, and harmonically the music is based on the tonic-dominant relationship (which, might I add, is common in nearly all romantic music until Scriabin), doesn't make it any less romantic. Romantacism was about using music as an emotional form of experession, without the niceness of the Style Galant. Even the modulations to remote keys in the Appassionata (which Beethoven pioneered) are typically Romantic.
I am sorry you think I am misguided on my understanding of what romanticism is. Perhaps I can illustrate it some more.
You talk about using music as an emotional form of expression, "without the niceness of the Style Galant." Well, Sturm und Drang predates Beethoven by a lot. Haydn and Mozart (let alone maverick Clementi) pretty much everywhere match your description. The Empfindsamer Style is just as classical, and Beethoven (all Beethoven) is well rooted in it.
Beethoven did not pioneer remote modulations, you find them everywhere in Haydn and Mozart, and in fact further back in Haendel, Bach and Scarlatti, all of whom were quite familiar to Beethoven.
What sets apart Beethoven from his predecessors is not a fundamentally different aesthetic, but rather his personal philosophical approach to music, which is full of the spirit of the French revolution. Much of what you feel is bigger and stronger is simply the result of Beethoven having bigger and stronger instruments coupled with his personality. Was it Goethe that called Beethoven "ungebaendigt"? (sorry, no patience for umlaut).
The clue, though, is that Beethoven's philosophical thinking has just as much Hegel as Rousseau in it, and that braids it to the music of Mozart and Haydn much more profoundly than to that of any of the romatics, perhaps save Liszt, Brahms and Wagner (sorry Schumann, no soup for you).
So, dear, what is it that I am so sorely misunderstanding about romanticism?
