Maybe it's not about mining? Maybe the power system needs to be strengthened or reconstructed? I believe that if there is a lack of electricity, it should be added, not banned mining.
Yeah, in reading the article, they're dealing with energy shortages just like everyone. It's understandable to crack down on excessive uses of electricity, and a mining farm certainly qualifies. This would be a big deal if these crackdowns were in US where a third of the mining comes from, but in Georgia, it's not going to change anything for the rest of us.
Something you'd never guess though, is that the third largest mining country is Kazakhstan, which is right across the water from Georgia. I'd suspect they're going to be dealing with similar electricity issues, and perhaps Georgia cracking down on mining is just a sign of what's to come for Kazakhstan, which could have a relatively large impact on the entire industry.
