How will this impact Russia's will to continue to supply gas and oil to Europe? Is Europe paying them in euros or some other currency? Where is it "stored"? If Russia's money is frozen, what use is it? Or even if it's not frozen, but they cannot use it to buy goods and services in exchange, then why would they bother selling the oil and gas?

Shutting down gas infrastructure is far more complicated that "turning off the spigot", especially when the people who know the correct order of buttons to push and knobs to turn work for British Petroleum and friends. Restarting those systems is even more complicated.

Shutting off the gas supply to Europe likely means self destruction of their gas production industry, because they will make drastic mistakes.

Russian organizations may receive euros as payment, which are still usable in Europe to buy things. This gives the EU a huge level of control over Russian spending in their markets; if they pay less, it's not like Russia can just exchange some rubles for eruos, they have to deliver products and services (which now cannot go to Putin's war effort).
