As posted in here earlier too, banning religious organizations don't work. Its true that the WT as an organization will be dismantled and no legal structure will exist from now.
However, in religious groups, its the people who make the organization, not the other way round. WT is not a strict corporate entity with employees moving out to other companies if their organization collapses.
WT is an ideology more than just a legal entity. You legalize them, they flourish. You ban them, they go underground. Banning them does not assure that their adherents would abandon their beliefs and adopt others.
For a greater part of their life, my parents were active JW's in a banned country. Expats though. No branch office, no kingdom halls, no singing, no contributions, no literature (except for those brought in by expats who got them from their home countries). No legal entity existed. Occasionally a circuit overseer would fly in and have a 1 day visit with the publishers and flew back the same evening. However, core beliefs remained the same. Disfellowshippings were announced, Elders flew in to neighboring countries to attend schools. Expats went to their home countries for their medical treatment and locals prepared legal affidavits that they personally wish not to take blood during treatments. Baptisms were conducted secretly at homes or crowded swimming pools. Expats reported their preaching activity to their home country, etc.
Religious groups can be banned, but ideologies cannot. People die as martyrs for their beliefs rather than just compromise with the ruling state. Countless ISIS soldiers died for their insane ideology, whereas scores of Christians were massacred by ISIS in genocide for being Christians. Patriotism and Religious fundamentalism has given rise to unimaginable list of such martyrs, who are willing to bear persecution and die for their beliefs, no matter how nonsense we find it to be.
