The government won't forbid the sale of transistors and solder. They don't have to, for two reasons.
Firstly, nobody can build a computer to the standard of a contemporary desktop out of transistors and solder. It simply can't be done, even if you don't care about its size or power consumption. You can build a little 4-bit computer, but that's no use to you. So they don't have to prevent all unsecured computation, they just have to prevent you doing more than, say, a billion cycles of computation.
Second, even if the bar is much lower than that — say, you can buy all the chips you need, you just can't buy them preassembled into circuit boards — that's already an effective suppression of general purpose computation. Maybe you personally have the skills and the time to build a computer from those pieces, but I and most people don't. So I've been effectively prevented from computation. I won't write programs and post them on the net, and the online programming communities will dwindle to a small bunch of experts.
And once almost nobody builds or uses general-purpose computers, it's much easier for the government to say "We can't think of a legitimate reason you need a computer, therefore, anyone who has one is a terrorist/pirate/communist." QED.
