The kind of argument cinepro puts forward ('Some jobs might not be offered if there was a minimum wage') are completely without force unless they are actually based on evidence of a quantitative kind:
How many jobs are not offered as a result? Some, no doubt, but enough to matter?
How many workers do in fact benefit from the wage rise, and to what extent?
To the first point, it's awesome that you're actually acknowledging the possibility that a minimum wage could hurt job creation. Usually, the focus is entirely on existing jobs (and the assumption that existing workers in existing jobs won't change).
The CBO did appear to take a stab at estimating how many jobs would be lost, and these were their estimates back in 2014:

So if we're losing that many jobs, I can only imagine how many aren't even created, since the math for starting a business that depends on low-skill labor will have drastically changed.
And as for:
Then that is cancelled by the contrary that if you allow an employer to pay a full-time worker less than he can live on, that employer is expecting the government, via welfare, to subsidise his business.
I live in an economy that had has a minimum wage for some time: the rate of unemployment is comparatively low, and many businesses that want to hire workers for jobs at the minimum wage cannot find people to fill them.
Which economy is this?
If a business can't find people to work at the minimum wage, then there is no need for a minimum wage. It's totally superfluous. It would be like the government telling In n' Out they had to charge at least $1 for their hamburgers. They would say "great, but we sell all we want at $2 a burger." If the minimum wage is $10/hr and an employer can't find people at that rate, they'll have to pay more so their "minimum" wage is higher; the market price is already higher.
For additional data and food for thought about how the minimum wage affects poverty and wages, here are some more CBO predictions from the report.
The increased earnings for low-wage workers resulting from the higher minimum wage would total $31 billion, by CBO’s estimate. However, those earnings would not go only to low-income families, because many low-wage workers are not members of low-income families. Just 19 percent of the $31 billion would accrue to families with earnings below the poverty threshold, whereas 29 percent would accrue to families earning more than three times the poverty threshold, CBO estimates.
Moreover, the increased earnings for some workers would be accompanied by reductions in real (inflation-adjusted) income for the people who became jobless because of the minimum-wage increase, for business owners, and for consumers facing higher prices. CBO examined family income overall and for various income groups, reaching the following conclusions (see the figure below):
-Once the increases and decreases in income for all workers are taken into account, overall real income would rise by $2 billion.
-Real income would increase, on net, by $5 billion for families whose income will be below the poverty threshold under current law, boosting their average family income by about 3 percent and moving about 900,000 people, on net, above the poverty threshold (out of the roughly 45 million people who are projected to be below that threshold under current law).
-Families whose income would have been between one and three times the poverty threshold would receive, on net, $12 billion in additional real income. About $2 billion, on net, would go to families whose income would have been between three and six times the poverty threshold.
-Real income would decrease, on net, by $17 billion for families whose income would otherwise have been six times the poverty threshold or more, lowering their average family income by 0.4 percent.
