Is sharing a taxi from a prohibited area, or working in bakeries that do not adhere to the salt standard in subsidized bread, or buying from them, considered unlawful (haram)?

Laws that serve the public interest must be adhered to in obedience to the ruler. As for those that do not serve the public interest, or whose benefit is not predominant, they are not obligatory to adhere to except outwardly. If you violate a law of the first type (serving the public interest), there is no blame upon you for consuming what you bought or benefiting from what you agreed upon with the car owner, provided you commit not to violate it in the future. As for laws related to the operation of bakeries, it is forbidden to violate them if it results in harm to people. If there is no harm, then the matter is broad.
