What does "democratic access to their country" even mean? The tourists visiting their country don't vote, so you don't mean literally. And any random rationing system you put in place will be inherently unfair in some dimension.
The work "democratic" does not always directly relate to governing a country, but also making something accessible to all without unnecessary limitations - similar to the right to vote.
Do I as non-citizen have a right to vote in whatever country I want, just because I have an opinion on the matter being voted? Access to citizenship is also limited by descent, wealth, or your conscientiousness. It is also ‘unfair’ if you interpret this word as ‘not instantly accessible to anyone who expresses interest’.
