"my 30 minutes is more valuable than a tshirt's cost" Of course, I know what you mean. But consider, at least for a moment, that the cost of that t-shirt to you includes the wages paid to the cotton pickers, thread makers, cloth makers, cutters, stitchers, packers, transport and warehouse workers, and the amazon delivery driver, who will contribute to making that t-shirt and getting it to your door. So in a way, you're saying your 30 minutes is more valuable than however many minutes of all those people's lives that would have to be spent to get you a new t-shirt. There's some profound insight into how economics works to be had when you truly consider what it means to trade off your time and the value of your labor output, against the time and labor of countless people, all put into supplying you with stuff.
