People tends to copy things that they have seen successful, and at the same time when more services are offered, it all goes down to whose service is better. I do not think it is a crime to follow a trendy business, nor is it forbidden by law.
We want more Bitcoiners to start unique online/offline businesses, especially those they care about or love, and that are able to sustain them sufficiently without toxic competitors popping up from somewhere, with little to zero talents, to do thesame things, steal away customers/income, add little to no value to the system.
True that, it is good to have more unique services, but does the law forbid people from doing the same kind of business? If a new business that offers the same kind of service gathers more customers, and even the customers of the first one have moved to the new one, this means the first one established is not giving satisfactory service. For customers, competition is good because customers often benefit from this competition.
Then the much needed creative ones may eventually leave the system for better one, and things become stagnant or degenerate into fiat-like system.
If the first one is to leave his business, then this mean is not competent enough to maintain his client. Why suffer from poor service from the first established when the newly established one give way more benefits and better service? I am stating in a customers point of view. Monopoly had long been regulated by the government, as long as the item or service is not exclusively designated to a company or individual (like patents and copyrights, trademarks, trade secrets, licenses), I do not find anything wrong if another company offers the same service.
The only time it may be OK to do similar businesses is if the original businesses aren't living up to expectation such as delivering good quality products/services. Or if the original are becoming too crowded, congested, slow and overwhelming to the owners. Or their products/services have become unaffordable or more expensive due to low supply and high demand
It is a free market, it is unfair for anyone to monopolize a non=exclusive services and it is not beneficial for customers. In this kind of situation, if a company wants to secure customers, they must do their utmost service rather than shutting down competition.
