just recently Israel ban Bitcoin because it has been perceived to be a tool to finance their enemies, but the questions is, can this ban change anything?
Can you link me an article? Based on my 10-second Google search, Israel's attempts to ban bitcoin was in 2018, but you're claiming that it's recent.
As for if a ban can "change anything" — of course it does. Anyone that will be caught transacting with bitcoin can get arrested. That literally changes everything for the people in whatever country bans bitcoin.
