That analogy works for app code, it doesn't work for technologies, library, frameworks, algorithms. Why build a compiler for this app? YAGNI! makes no sense.
Yup, because perfect competition is fundamentally the same as the salary cap, except for companies instead of employees. Specialization leads to natural monopolies at company level just as it does at personal level. Besides, the term monopoly only makes sense when it's state-enforced. In a free market it loses meaning since every company has a monopoly on their exact product.

This is the definition of brainwashing. You had a false choice between person A and person B who are mostly the same some 4 years ago, and now _you_ are responsible for every stupid policy they enact.
There are no core tenants of democracy other than majority rule. The actions you listed (with the exception of canceling elections) do not actually destroy the ability for the majority to rule. In fact, one common tactic of democratic states is to employ referendums for laws that infringe on the rights of a minority, thus shifting the moral blame onto the population when convenient.
