Some people have legitiment business interests in tax-haven type countries that are not about avoiding taxes. No country is just purely a tax haven with no other ecconomic activity after all.
In theory a blanket ban on crypto could harm innovation. This was much easier to believe at the beggining of the hype cycle when it seemed like someone might actually do something useful with blockchain tech. Kind of hard to believe at this stage.
I feel like inheritence tax is kind of pointless by itself. Most people dont just suddenly die and have time to distribute their assets pre-death.
Limiting housing investment might make cost of living go up. Its not like houses just appear out of nowhere. lots of people cant afford to just buy/build a house. Rich people buying houses and renting them out helps fill that gap. It doesn't always work out as ideally at that, but the other extreme of severely restricting real estate ownership would probably screw over poor people too who do not have sufficient resources to get a mortgage. They still need somewhere to live.
I dont really know what independent auditors means precisely. IRS/CRA/etc are already pretty independent. They could be better funded though.
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.
Ultimately, people as a whole like to work. They dislike working under poor conditions or doing jobs that don't feel rewarding. A law like this would generate a lot of change, but I just don't see that change being disasterous given sufficient adjustment time.
