nobody has ever done pure capitalism; social systems are always a messy mix of modalities
but some societies are more capitalist than others, like those where markets rather than regulators make collective choices, and those tend to be the more prosperous and competent societies
'running your company with profit as your goal' predates capitalism by several millennia, and for that reason among others it is totally inadequate as a definition of capitalism
quoting wikipedia:
Capitalism is an economic system based on the private ownership of the means of production and their operation for profit.[1][2][3][4] Central characteristics of capitalism include capital accumulation, competitive markets, price system, private property, property rights recognition, voluntary exchange, and wage labor.[5][6] In a market economy, decision-making and investments are determined by owners of wealth, property, or ability to maneuver capital or production ability in capital and financial markets—whereas prices and the distribution of goods and services are mainly determined by competition in goods and services markets.
market competition is fundamental to capitalism.
calling a competition-prohibiting government decree like this 'capitalist' because private companies presumably lobbied for it last millennium is like calling iran or venezuela today 'democratic' because their dictatorships were voted in by their citizens many years ago
you say, 'capitalism [can] be, to some extent, prevented from doing those harms by strong regulation' but in fact in this case the strong regulation is what is doing the harm, not whatever vestiges of capitalism remain after the regulators removed competitive markets, voluntary exchange, price signals, and private-sector decision-making
