- Easy to "register" a business at least in USA ? Very easy. Could be done in 30 mins depending on the state you register in.
- Easy to "build" a product or service ? May be. If you have tons of experience in that product/service already. Usually not. In software world, I will concede that it is relatively easier to build things these days because of the ecosystem of libraries/open source/frameworks/tutorial/youtbe etc but easy doesn't mean simple and no guarantee for success.
- Easy to "sell" the product/service ? Very hard.
- Easy to "operate" the business ? people/customers/issues/tickets/hiring/legal/tax/accounting/ops/conflicts/lawsuits/contracts/govt bullshit blah blah. Not even close.
- Easy to "sustain" the business over a period of years ? (Read 7-10 years for anything real). hahahhah.
