Some of these are a bit different in scope to some of your points, but here a few things I believe aren't really covered:
Predatory hiring: Hiring key employees from competitors primarily to weaken them rather than to benefit from the employees' skills.
Patent abuse: Using a large portfolio of patents to stifle competition rather than to protect legitimate innovations.
Regulatory capture: Using influence to shape regulations in ways that benefit the monopolist and create barriers for potential competitors.
Killer acquisitions: Buying potential competitors primarily to eliminate future competition rather than to integrate their technology or talent.
Data hoarding: In digital markets, collecting and refusing to share data that is crucial for competitors to enter or compete effectively in the market.
Self-preferencing: In platform markets, giving preferential treatment to one's own products or services over those of competitors.
Vaporware: Announcing nonexistent or deliberately suboptimal products or features to discourage customers from switching to competitors' existing products.
Predatory hiring - banning this would be preventing competition in the labor market and be extremely bad for workers. Also unproveable.
Regulatory capture - the government regulators are not going to sue themselves
Killer acquisitions - already illegal to engage in acquisition to form monopoly
Data hoarding - the government can't force you to share things for free. That violates the takings clause
Self-preferencing - this is such a long standing and legally permitted practice that it is not plausible to make illegal. e.g. every grocery store has a store brand that they favor.
Vaporware - if this is a provable lie it is already covered by fraud statutes, and it would be such a stupid move by the company that I don't believe it actually happens
