The matter of fact is that only very few countries in Europe can "afford" to get by without Russian gas or other resources. After all it is the home to the continents largest concentration of natural resources.
There is only so much global production capacity, so much bandwith in terms of logistics, that can compensate for that. It's not like we can suddenly tap a new continent full of resources to replace Russia, reality ain't working like that.

FSRU Independence has sufficient capacity to deliver enough gas to serve 70~100% of the yearly needs of the three Baltic countries, depending on how you count. Of course it remains a question of who supplies the LNG, but it gives the countries a backup, an ability to pick the suppliers and an ability to make politically important decisions, even if it means paying a little more.
