The author focuses on "ideas" but ideas are only the seeds that sprout.
I am convinced America's Founders were indeed inspired by God - they looked beyond the "ideas" (knowing the future would always hold new, yet undeveloped tyrannical ideas) and focused instead on the conditions and not allowing those seeds to sprout
Divided Federal government powers. Broad powers to the States. Taking money creation out of the hands of central planners (we've already destroyed that). Letting the population hold arms, confirmed inalienable rights, freedom to worship, etc.
Don't worry about "the ideas" per se - rather, focus on not allowing the conditions they need to grow into stinking weeds
Big parts of it:
Freedom of speech and press, so people can communicate that things are going wrong.
Right to arms, so any tyranny would be outnumbered by armed populace.
Right to jury, to make it harder to imprison dissidents.
