This doesn't work in practice. Look at how Senate Republicans have weaponized the filibuster in the last 20 years. A 40% veto is conceptually similar to your repeal process and it results in gridlock and nothing getting done.
It is harder to build than to destroy. If laws can be trivially repealed no one will be willing to commit to long term things. We're seeing that right now with the destruction of US soft power, economic power, and global leadership.
There is a difference between long-term stability in foreign relations and long-term stability in citizens' freedom. The latter is supported by the absence of restrictions, i.e. the absence of laws and regulations.
The only people wanting stability in restrictive laws are those profiting from their legally guaranteed niche, typically of the rent-seeking monopolist kind.
The absence of laws and regulations enables exploitation, not freedom. We've seen that over and over. Libertarianism gives us the "freedom" to have monopolies price gouging, locking the fire exits to ensure we don't leave before our 16 hour shift for pennies is over.
