Reading your comment fully (something I should have done), I see you address the differences in the analogy. Sorry.
Perhaps the cost situation will change over time. Perhaps, in coming decades, the ability to fab microchips will itself become something achievable for thousands instead of millions of dollars. And as for regulation: That only matters if you're selling. If you're researching or making it for personal use, the FCC doesn't (or shouldn't) matter.
