Violations like that are charged all the time. This particular offense was already charged against Trump's lawyer, so it makes sense to charge Trump who directed Trump to do it. It wasn't just a campaign finance violation. It also was a major financial misstatement, even fraud telling the election bureau, the IRS and state officials this was legal expenses, which it clearly wasn't. There's no way no how one can make the claim "not a big enough deal to charge". Things like that and even more minor get charged all day long. It's just that there is a very long history of Trump and his goons interfering with this charge getting brought and making a much bigger deal about it.
