"After Supreme Court has stated, an individual has the right to earn a living, to pursue an occupation of one's calling" — how could one exercise this right, and then be taxed on such an exercise?
This is because most people do not understand what income is. "Income" is not defined in the Constitution, and therefore the ordinary meaning applies. Why is this? Because the original intent of the Constitution as ordained by the people was the "specific" as to congressional authority. Congress had the right to tax, as a result of paying for Government services, but the 9th and 10th amendments have the people reserving and retaining the right to earn a living!
"The right to earn a living" — "At the common law," wrote William Blackstone, "every man might use what trade he pleased" ([1765] 1979, 1:415). Link

The Uniform Commercial Code (UCC) defines "consumer goods" as goods that are used or bought for use primarily for personal, family, or household purposes. This definition is provided in § 9-102 of the UCC, which governs secured transactions. Therefore, household goods are considered consumer goods under the UCC when they are used primarily for personal, family, or household purposes.

"Our goal is not to rewrite the tax code."
The way the law works is original intent. As noted, the courts have already ruled in several cases that "household goods", "consumer goods", "items that are for personal use", "that are not for commercial use", that are not-for-profit and/or gain, is exempt property. The Uniform Commercial Code identifies as much, under article 9 section 201 and 209 — household goods, consumer goods, exemption!
