If we are able to lift the restrictions we can supply Europe with Oil and more impotently Liquefied Natural Gas. This helps reign in Putin as it directly removes cash from his pocket and cuts into his power over Europe.
If we start exporting, it will only be a little bit of light sweet from the Gulf Coast region. Our net will still be importing ~7 million BPD. We won’t be making any real dent in Europe’s oil needs.
There will be an occasional shipment of other to meet upset conditions, but economics and our demand are not going to make us a net exporter. Not for a couple decades at least and only if high price continue.
And I shouldn’t even try to make multi-decade predictions.
