Point two is why I threw a "basically" in that sentence. Yes, you are technically correct that the state can change it with a 7/8ths majority. However requiring a supermajority that high is a nearly unprecedented requirement for the legislature and it is one that is going to be nearly impossible to achieve.
I honestly don't know what you consider "false information" here beyond me saying "basically no way" for something to happen when it is realistically unfeasible.
