Support the coin, how exactly? And why does the government need to control things, do you really believe that without the government's monopoly on the use of force, accompanied by the perpetual threat of exercising that monopoly, society would descent into anarchy? Have you ever heard of the political philosophy of Anarcho-Capitalism?
A lot of government regulations exist to perpetuate the status quo, and ensure those who hold power will continue to maintain their hold on it. For example, government regulations throw up artificial barriers that prevent all but the already wealthy from investing in companies at the stage in their growth when investments yield the largest returns. In the US, unless you are an accredited investor (for which an your net worth must be >$1,000,000 and annual income >$200,000 for the past 2 years, with the expectation of maintaining that level of annual income going forward), it is illegal for you to invest in startup companies. People who are not in the top 0.5% have to wait for companies to hold an IPO before they are allowed to invest in them, and at that point the gains to be had will be much lower than if you invested earlier.
To put this in different terms, if Bitcoin was regulated like this from day 0, it would have been illegal for people like you and me to invest in it until the price broke 5-10k per coin.
Cryptocurrencies are becoming successful despite the government, not thanks to it. Institutional investors who believe crypto has achieved all the growth it possibly can without formal government regulations are still stuck in the bubbles they have created for themselves, where they believe anything that doesn't fit into their perception of how the world works cannot possibly work. They are the same people who said Bitcoin couldn't possibly work or deserve it's valuation when it was $20, and again when it was $200, and yet again when it hit $1000.
