Of course, in most societies there are elements of both, often called the interventionist state or the "mixed economy." But, nonetheless, the basic institutional alternatives are liberty or coercion.
This often seems difficult for people to fully appreciate or understand. We select where we live, we accept or not accept a job offering, we decide on the furniture in our home and what (if anything) we will read in terms of books or magazines, or to watch on television. We pick our friends and choose the clubs and associations we want to join. A thousand other everyday choices and decisions reflect our freedom in still much of what we do.
Yet, at the same time, we take for granted many aspects and facets of our lives where such decision-making is narrowed or co-opted for us by those in political authority. We are compelled to pay into the government pension system called Social Security; we are taxed to pay for types and degrees of medical and health care that we may or may not desire or consider worth what the government garnishes from our salaries to pay for it before we even see a penny of our earned incomes.
The government regulates how business is done, under what terms and conditions an employer may hire a worker, what products may be produced and with what qualities, features and characteristics, and sometimes the price at which the good or service may be sold.
