If a company has a persistently high market share and has had for a long while, it has an effective monopoly whether or not it has ineffectual competitors.

However I believe the reason nothing changes despite these obvious market distortions is that super profits are self perpetuating: companies invest in politicians to keep the distortions in place. The technical definition of monopoly is just a smoke screen.

No, it doesn't. Making up your own definition of monopoly (or the meaningless "effective monopoly") doesn't make it true, valid, or useful.

The Supreme Court has defined market power as "the ability to raise prices above those that would be charged in a competitive market,"(8) and monopoly power as "the power to control prices or exclude competition."(9) The Supreme Court has held that "[m]onopoly power under § 2 requires, of course, something greater than market power under § 1."
