What infrastructure remains the preserve of only a few in any business enterprise?

Some examples of infrastructure that may remain the preserve of only a few in a business enterprise include:

2. Specialized equipment and machinery: Certain industries require specialized equipment and machinery that may be expensive and difficult to obtain. Companies that have access to this equipment may have a unique advantage in the market.

3. Exclusive partnerships and relationships: Some businesses may have exclusive partnerships or relationships with key suppliers, distributors, or other stakeholders that give them a competitive edge in the industry.

4. Intellectual property and proprietary technology: Companies that have developed proprietary technology or intellectual property may have a unique advantage over their competitors who do not have access to the same resources.
