c) Immigrate to another country with no or at least territorial taxation, such as Monaco, Hong Kong, several Caribbean and Pacific nations.
d) Become a permanent traveler and switch countries regularly, making sure that you do not personally become a tax resident in any of those countries. The time to become a tax resident varies, but in many countries it is 183 days.
e) Structure your company's tax residency to be in a country with no taxation. Search around for "company tax residency" to understand how this works. Companies are often taxed "from their location of central management". If you have an online business, make sure you are reasonably private to convince your current country's local tax authorities that the management is done elsewhere. However this can be really hard to do if you solely operate the company, at which point I understand why
