For offshore restrictions - you as a country lose all existing assets already there. A lot of people will move their business to a better countries, providing less restrictions and eventually taxes for them. Probably election loss and further dismantling of all these laws by disgrunted businessmen using their pocket political forces. If will hugely depend on the collective size of economies doing the ban.

For housing - its tourists plus rent seekers vs. regular citizens. You hurt one group and you benefit another and vice versa. There is no win win scenario here, balance must be found. I personally vote for regular citizens, even if tourism industry will be hurt a little bit.

For inheritance taxes - no downsides.

For token ban - no downsides.
