I think you first of all need to define "short term"
Next you need to consider what happens without such short term trading.
Here's what you should consider:
Society needs a vibrant economy. Vibrant ecoonomies need businesses that can compete on the world stage. These business ventures needs money to grow. That money has to come from somewhere. The choices are limited:
1 ) Private Sector
2 ) Public sector
When deciding who should have money to lend here's the things to consider:
a ) funds are always limited.
b ) less money is allocated more carefully than more money
c ) expertise is always limited
d ) people have agendas that may not match those of the venture
When considering these factors it is important to be objective. Ask what you would want if you were starting up a business. refering to the above points:
a ) as a businessman, would you prefer the funding of your business to be decided on its potential success, or because it suited government policy?
b ) bearing in mind how you have spent money when you have had access to more or less of it (borrowed or otherwise) would you prefer, as a taxpayer, that business be funded from the bottomless pit of public money, or from private investors.
c ) would you prefer, as a businessman, to take your advice from government experts or industry experts? Are government experts any more right than industry experts?
d ) would you be happy as a businessman if your company loan was granted only on the basi sthat you promote/assist some government scheme, or would you prefer the business to go in th edirection of greatest potentail profit?
If you come to the conclusion that private enterprise, funded by private funds is a good thing, then you have to start thinking about how market trading restrictions may inhibit private investment.
Start up businesses are generally funded by business angels and venture capitalists. They lay their money on the line when nobody else is interested. Their motivation for getting involved is simple: profit. tak ethat away and thefunding for new business from the private sector will evapourate. In order to achieve the high returns tha go with the high risks entailed, most angel sand VCs require an "exit strategy" that will enabl ethem to sell on all or part of th enurtured business after a short timeframe. If they see no exit strategy, they will put up no money. The exit strategy fvaoured is a float on the markets or "Initial Public Offering". the markets allow late stage investors to buy a more mature (and hopefully now profitable) business from the VCs. The VC gets a tidy profit, the late stage investors get a share in a (hopefully) still expanding business.
So much for VCs. What about those late stage investors: why should they invest? Once again they are hoping to make a capital gain as the business matures, so they are looking for an exit too. Why should they invest without one? The business amy have alimited track record of profitability. Without business growth and capital gain your money would be better off in FTSE100 Utility shares or perhaps even the bank.
Their exit strategy is straightforward: sell into the marketon which the shares are listed. the ease or difficulty of this is determined by the liquidity of the shares, ie how many buyers and sellers are trading on any one day. The more short term traders trading a share, the higher this liquidity. Having said that, during crashes liquidity dries up as players sit on their (paralysed) hands, so the more liquidity, th eless likely it is you will ever find yourself locked into a desceending share price. More liquidity means less risk.
More liquidity also means better price discovery. The more times a day a share is traded, the more accurately you know it sprice. If a share is traded once a year, god knows what the price is at the 6 mont point. Investors have no way of knowing whether they are making money or losing money (a bit like housing at the moment). nce again, that will deter other investors from buying or selling (if you live in a town with one shop selling TVs are these good or bad prices? Who knows.)
So you an see that liquidity through short term trading is linked directly to a healthy private business environment.
Maybe however you think governments are good at deciding which businesses are good for a country. In my experience they are good @
taxing companies that are good for a country.

Companies are stuffed full of managers whose only concern is meeting their own short term targets before moving on,
usually they want to create an empire so that their salary looks "reasonable" by comparison with turnover.
incentivise them take more pay in shares.
