If Europe does't buy gas from Russia then that leaves Qatar and the US. Qatar does sell a lot to Europe (hence you'll notice how "friendly" Europe is towards Qatar) but is vulnerable to instability in the straight of Ormuz.
The US are making a fortune on gas at the expense of Europe an it's not that the promise to buy gas is meaningless because unenforceable within Europe, it's that it was already happening in practice. And that makes Europe even more dependent on the US (while the complaint was that we could't buy gas from Russia and depend on them).
