I'm misspeaking. My apologies.
States have power not specifically given to the federal government(currency, foreign treaties, etc.). They are free to make laws that govern their own state, but those laws end at their borders. The Constitution also has a "supremacy clause". It grants federal laws supreme priority over state laws.
For alot of federal laws, they're written in a way that states can work with or around them. For instance, federal law says possession, use, or distribution of illegal drugs is prohibited. It doesn't specify what drugs are illegal. That is decided by state law which is why we've seen a huge increase in the number of states legalizing marijuana and even had Oregon just decriminalize hard drugs.
For your example, governors don't create laws, however, state governments have the same checks and balances system the federal government has. They have a legislative branch made up of reps from each district who create and pass laws within the limits of the Constitution and federal laws. If governors create policies that harm citizens, then the legislative or even judicial branches can step in to correct it. Citizens can vote out the current governor, petition their district rep to try and get the policy corrected, try and sue the state government, or move to another state. So, moving isn't their only option, but it is by far the easiest.
The federal laws themselves aren't necessarily the problem. There are laws like the civil rights act and equal employment opportunity. On the surface they are fantastic laws that protect against discrimination. The way it is used, however, does the exact opposite of what it was supposed to protect. In many instances, companies have to hire based on skin color or gender instead of qualifications. It hurts the company, citizens, and country as a whole.
The core values of the Constitution ARE individual rights. The federal government's power was given to protect those individual rights. How the government protects those individual rights is the difference between all the political parties.
Even if we had a 100% secure way of voting online, I don't care for it. There's no reason 99% of the people in the U.S. can't vote in person. If someone is out of the state, out of the country, sick and dying, we can still find ways that would allow them to vote in person.
Require an ID, make it a national holiday that shuts down all stores or turns them into voting sites so lines aren't awful, and go vote.
