Testing UBI is always an excuse to avoid UBI. UBI is as obvious as slavery abolition or basic universal healthcare. You don't need to worry about people choosing unemployment, because you just need enough HR workers to call everyone 5 times a day with awesome job offers.

City secession is probably necessary for UBI, as it can be easily implemented at city level. City politics still demanding power hierarchy as prize for politics victory makes demonic evil oppression a perpetual social feature. UBI is especially suited to cities because police, homelessness, education are in their budgets. UBI eliminates crime and homelessness. Privatizing education and daycare with stipends for children is a budget reduction, with far more likely than not higher educational achievement.

Cities typically depend on property taxes for nearly all funding. Density weighted property taxes can pay for entirety of UBI, with those living alone in large spaces subsidizing those who live in small spaces. Adding small income and sales taxes can eliminate payroll taxes. Income taxes that are equal between businesses and individuals up to say $100k, means that $100k in employment income can be tax free if it is not a deduction to businesses. Business losses can still get tax refunds. Investor income no longer getting tax breaks is justified because investor class also gets UBI. This means lower personal/business tax rates. No more need for payroll taxes. EI not needed. Either save for a rainy day, or borrow (cheaply because income to repay is assured) from future UBI. UBI replaces future retirement benefits. Sales taxes also mean lower business/personal tax rates, without caring too much who made what you are buying. But security guarantees/tributes are far cheaper than Federal fascism.

Before you worry about pig slime multimillionaires threatening to leave your city due to end of slavery, and end of zionazi warmongering fascism, know that the best places to live on the planet are those with no crime, homelessness, and great restaurants, entertainment and retail experiences made abundant because people can afford to patronize them. The Zohran in NYC should propose UBI and secession instead of hierarchy bandaids.

When Ford and Carney promise to give all of Toronto tax money to Alberta climate terrorists and Ukrainian nazis, then the power redistribution to people provided by UBI, and secession, for Toronto is necessary. Everyone is still free to donate their money to Alberta MAGA nazis, and Sarnia Ukrainians gets more influence over remaining of Canada's devotion to a war on Russia, and Canada's submission to US and Zionaziism is unimpeded, with Toronto residents free to donate to Israel or to a coalition willing to nuke Tel Aviv, if no multicultural singe state or 2 state implementation not immediate. Certainly, a part of Toronto tax revenue needs to be set aside for nuclear deterrents to those who would interfere with secession/UBI structure, as well as tribute to pacify nearby powers who would otherwise make such threats.

Social unity is a powerful benefit. It is far stronger with UBI, and liquid democracy easily achievable through crypto society infrastructure that already exists. Toronto secession/governance/UBI is forerunner example to make all of Canada follow. Social unity without sacrifices to MAGA/Zionism/Warmongering corruption is better social unity. Compromises to evil is by definition fascism, and theft of your wealth for evil. UBI is not theft. It is redistributive power, wealth and quality of life enhancement.
