No doubt govs will always try, but who would want to use that over btc?

It’s more that the vast majority of people *want* a government and *want* that government to provide some modicum of a safety net, security and a provisions for general welfare, so there is an in-built market for taxation by which the government can induce demand for its own currency. I predict this dynamic will persist.
Could you see a situation where taxes are paid in btc?
