It's an option but that I also see Monero as an option for transactions at least. I don't see why we can't hold our wealth in Bitcoin by default and then switch to Monero if we're going to be making a lot of transactions. That's why I can't really get behind the "no second best" mentality. I like Bitcoin because I see its benefits and thus I support it, but I also think that there are benefits to a few altcoins like Monero for privacy.
