Creating as much freedom as possible for principled individuals--while not impinging upon another's freedoms--is one of the fundamental assumptions that MBM rests upon. Whether it be an entrepreneurial employee in the firm, or a citizen in a society, this tends to be critical for long-term prosperity.
In general, every decision a government makes for an individual--whether it be allowing individuals freedom to make choices about what they say, what religion they follow, or how they spend their money--is a tradeoff of freedom for some other thing.
In the link below, you can calculate your entire tax burden (I suggest taking a strong drink of your favorite beverage first). Seen all at once, it's hard not to think about the economic freedoms being given up, and what's being traded off for them. Instead of you deciding to spend that $5,000 on education, a county clerk is spending it on X; instead of you deciding to spend that $10,000 on charity, the state government took it for Y; instead of you spending that $15,000 on your daughter's wedding, a politician is paying for Z (or perhaps to cover Z up). Many of the X's, Y's and Z's the government spends money are good things (national security, for example) but unfortunately many of those things aren't so good, aren't well implemented, and aren't necessarily what you would like that money to be spent on (say, if you're a pacifist supporting a war, or environmentalist subsidizing a farm with heavy pollution).
We believe that--in general--an individual can better use resources (in this case, her money) than a detached individual far away because she is the only person on the earth who is uniquely aware of her wants/desires, knowledgeable about her local conditions, and ultimately will be the one person who bears the accountability of spending her money well or poorly. For similar reasons, we believe that--in general--we want individuals in an organization to use their local knowledge and feel the good-and-bad of the decisions they make where it makes sense to do so (caveat: this doesn't mean we decentralize every decision all the time).
