In short, we as a species have had a lot of practice designing governments in the centuries since the US constitution was written, and by their standard America is a dysfunctional backwater.
The checks and balances between the branches of our federal state were designed without political parties in mind, and they’ll need to be restructured to minimize interdepartmental collusion and prohibit self-dealing at least.
The executive should not be the sole issuer of pardons. The judiciary should be responsible for enforcing the penal system rather than the executive. The legislature should not be a competition between two sports teams. The Senate and electoral colleges shouldn’t exist. Representatives should be elected proportionally by state rather than winner-take-all for each congressional district. Recall votes should be implemented automatically if a representative trends down into negative favorability. The president must be subject to the law, and it should be easy for the citizenry to recall them as well. Judges should not be allowed to affiliate with political parties. Nobody in the government (federal or state) should be allowed to maintain ownership or control over commercial entities, and they should be audited frequently and randomly to ensure they have no conflicts of interest. The top marginal tax rate should be 100% and kick in as soon as an individual’s income exceeds some reasonable multiple of the minimum wage, which should itself be pegged to consumer price indexing of the cost to raise a family. Every elected position should have term limits. Etc etc etc.
Metaphysics has bigger questions to ponder and doesn’t apply to physics. It’s a branch of philosophy, not science.
And quantization was the solution to an even bigger problem in physics, the ultraviolet catastrophe.
We know that matter and energy are quantized because that’s the only reasonable explanation for why blackbody radiation is distributed like it is. The classical Raleigh-Jeans law, which accurately predicts thermal radiation frequency at low temperatures, fails to do so for higher temps. Only quantizing the emission of photons produces blackbody radiation predictions which match our experiments.
