Is it considered forbidden to circumvent the inter-state travel bans—imposed by the government due to the pandemic—by booking a hotel with the intention of bypassing these laws to visit family?

It is obligatory to adhere to government directives that impose a ban on movement except with a permit in countries where the epidemic has spread widely, because these directives aim for the public interest and to limit the spread of the disease. Violating them and lying to the state is forbidden, out of obedience to those in authority in what is good and out of consideration for the public interest.
