This might not affect corrupt countries as it doesn't matter because tax money goes to politician's coffers but what about developed nations?
This will depend on countries government understanding and approach to crypto.
Some of the big businesses are monitored by government, therefore, government have first hand information of the organization income. Using cryptocurrency as a means of payment will only cost them sanctions, which may attract higher charges than tax.
