EVERY GREAT BUSINESS IS A MONOPOLY.
And thats a good thing for you.
Have you ever played Monopoly? Im a Risk kind of guy, but stay with me. Do you know why it was invented? To prove how “evil” monopolist business are.
“**Monopoly is a board game that originated in the United States in 1903 as a way to demonstrate that an economy which rewards wealth creation is better than one in which monopolists work under few constraints ** ”
There is one BIG, obvious and conceptual flaw on the game when compared to real life. Every turn, you roll the dice. The players and the boards are always the same until someone wins.
In real life, the market (board) changes. New players come along, kick the board to the floor and punches everybody in the face. Im looking at you Netflix and Spotify. Monopolies would deserve their bad reputation in a world where nothing ever changes. 
Think about it:
Blockbuster was a monopoly. Netflix came along with a right jab.
IBM was a monopoly. Microsoft and took over.
Apple Itunes was a monopoly. Spotify kicked it in the nuts.
Motorola was a (sort of) monopoly. Apple made every phone look like a cheap toy.
People were happy to buy a Motorola. Until they saw an Iphone. Player 1 eliminated.
People were happy to pay $1,99 per song on Itunes, now its absurd. Player 2 eliminated.
People used to like going to a blockbuster to pick a movie. Now thats stupid. Player 3 eliminated.
Everything changes. New boards come along. Players get knocked out cold.
New monopolies are good for consumers, it breeds new technologies.
Thats why there are incentives of new monopolies and also laws to stop them.
I see plenty of startups running around with products with no real differential . They try to convince people that they are a unique snowflake in a huge market. Most of the time, they are a slightly better version of something already out there. And they fail miserably.
If you want your business to succeed, you need a a badass value proposition. Then you can kick the competition in nuts. For real.
